When an organisation or company operating an LIR changes ownership status or stops serving as an LIR there are financial, IP address space and RIPE Database issues that need resolving. Therefore, the RIPE NCC must always be contacted when an LIR changes ownership or closes. In the case of an LIR ownership change, the LIR should contact the RIPE NCC at [email protected] Link: mailto:[email protected] . Only registered LIR contact person(s) can discuss the change of an LIR ownership with the RIPE NCC. The following steps are required to change the organisation operating an LIR: 1. Clarify the type of change: A takeover of one LIR by another LIR, closing one of the LIRs. A takeover of one LIR by another LIR, both remain open. A takeover of an LIR by a non-LIR. 2. Outline the details of the change, stating: The reason for the change of organisation. The name of the company/companies involved. The number of LIRs affected by the change. The RegID(s) of the LIR(s) affected by the change. 3. Present the following documents to the RIPE NCC: Confirmation from all parties agreeing to the change (See section 2.3). Updated list of contact person(s) (See section 2.4). Updated billing e-mail contact details, including any changes to VAT number. A new service agreement, if applicable (See section 2.2). Legal documentation supporting the name change, if applicable (See section 2.2). Overview of utilisation in all allocations (See section 2.6). Following any type of change (such as mergers, acquisitions or takeovers) of an organisation operating an LIR, the RIPE NCC will review the status of any IP address allocations that are held by the new organisation. When an organisation operating an LIR changes ownership, a new service agreement may need to be signed. The RIPE NCC will need to request a new service agreement from the new owners if: The organisation operating the LIR changes name, or The LIR wishes to change their RegID. The registration documentation from the relevant Chamber of Commerce, or its country equivalent, supporting the name change must be submitted to the RIPE NCC. The Standard RIPE NCC Service Agreement is available from the RIPE Document Store at: http://www.ripe.net/ripe/docs/service-agreement Link: http://www.ripe.net/ripe/docs/service-agreement If the organisation operating the LIR does not change its name and keeps the original RegID, the LIR can continue operating under the same service agreement. In cases where an organisation operating an LIR takes over one or more LIRs, confirmation of the takeover from all parties involved or their legal successors must be included. It is very important to notify the RIPE NCC, if there is a change of contact person(s). This is essential, as only registered contact person(s) can submit Internet resource requests to the RIPE NCC and provide updates to our internal registry files. If the contact person(s) of the affected LIR has changed, the RIPE NCC may adjust the Assignment Window of the LIR until the contact person(s) is up-to-date with RIPE NCC procedures and RIPE community policies. If there are no current registered contacts remaining with the LIR, a fax signed by the Managing Director of the LIR on organisation letterhead is required to implement these changes. These changes should include the new registered contact person(s) for the LIR. It is not necessary to obtain a new Registry Identifier (RegID) if the name of the organisation that operates the LIR changes. The RegID is merely an internal identifier used by the RIPE NCC to distinguish the various LIRs. It does not have to correspond to the legal name of the organisation operating the LIR. If an LIR insists on changing their RegID, a fee corresponding to the sign-up fee for a new LIR will be charged to cover additional administrative work generated. Please see the current version of the RIPE NCC Charging Scheme available from the RIPE Document Store at: http://www.ripe.net/ripe/docs/charging Link: http://www.ripe.net/ripe/docs/charging All transfers of address allocations from one LIR to another LIR (or to a non-LIR) require approval by the RIPE NCC. It is expected that all database objects relating to this allocation be correct and up-to-date before the transfer occurs. Transferred allocations containing a large amount of unassigned address space may be set aside and kept by the RIPE NCC until the other allocations held by the LIR are considered fully used (about 80%). Once the LIR has reached full utilisation in its other allocations, the reserved allocations will be made available to the LIR. For further details on allocation policy, please refer to the document "IPv4 Address Allocation and Assignment Policies in the RIPE NCC Service Region" available from the RIPE Document Store at: http://www.ripe.net/ripe/docs/ipv4-policies Link: http://www.ripe.net/ripe/docs/ipv4-policies In cases where an organisation operating an LIR takes over one or more LIRs, a takeover fee is due for every LIR taken over (e.g. if three LIRs are taken over, the fee is paid three times). All current outstanding invoices for the LIRs being taken over will also have to be paid in full. The transfer of address allocations also incurs a takeover fee and does not vary according to the amount of address space being transferred (e.g. if three allocations are being transferred from LIR A to LIR B, the fee is only paid once).

This document describes the procedures for the delegation of au-
thority of zones in the 193.in-addr.arpa domain. As of March
16th 1993 the RIPE NCC has been delegated the authority for the
193.in-addr.arpa domain from the root. Due to the fact that in
the 193.x.y address space blocks of 256 class C network numbers
are further delegated to local registries , the possibility ex-
ists to also delegate the zone for these blocks in the 193.in-
addr.arpa domain. This document describes some guidelines and
procedures for this type of delegation and the delegation of re-
verse zones for individual class C networks in 193.x.y.
A bit more explained
With the assignment of class C network numbers following the CIDR
(RFC 1338) model, in which large chunks of the address space are
delegated to one region, and within that region blocks of class C
network numbers are delegated to service providers and non-
provider registries, some hierarchy in the address space is
created, similar to the hierarchy in the domain name space. Due
to this hierarchy the reverse Domain Name System mapping can also
be delegated in a similar model as used for the normal Domain
Name System. For instance, the RIPE NCC has been assigned the
complete class C address space starting with 193. It is there-
fore possible to delegate the 193.in-addr.arpa domain completely
to the RIPE NCC, instead of each and every reverse mapping in the
193.in-addr.arpa domain to be registered with the INTERNIC. This
implies that all 193.in-addr.arpa resistrations will be done by
the RIPE NCC. Even better, since service providers receive com-
plete class C network blocksNCC, the RIPE NCC can
delegate the reverse registrations for such complete blocks to
these local registries. This implies that customers of these
service providers no longer have to register their reverse domain
mapping with the root, but the service provider have authority
over that part of the reverse mapping. This decreases the work-
load on the INTERNIC and the RIPE NCC, and at the same time in-
crease the service a provider can offer its customers by improve
response times for reverse mapping changes . However there are
some things that need to be examined a bit more closely to avoid
confusion and inconsistencies. These issues are covered in the
next section.
Procedures for the delegation of direct subdomains of 193.in-
addr.arpa
1. A secondary nameserver at ns.ripe.net is mandatory for all
blocks of class C network numbers delegated in the 193.in-
addr.arpa domain.
2. Because of the increasing importance of correct reverse ad-
dress mapping, for all delegated blocks a good set of secondaries
must be defined. There should be at least 2 nameservers for all
blocks delegated, excluding the RIPE NCC secondary.
3. The delegation of a class C block in the 193.in-addr.arpa
domain can be requested by sending in a domain object for the
RIPE database to <[email protected]> with all necessary contact
and nameserver information. The RIPE NCC will then forward all
current reverse zones inside this block to the registry, and
after addition of these by the registry, the NCC will check the
working of the reverse server. Once everything is setup proper-
ly, the NCC will delegate the block, and submit the database ob-
ject for inclusion in the database. An example domain object can
be found at the end of this document.
4. All reverse servers for blocks must be reachable from the
whole of the Internet. In short, all servers must meet similar
connectivity requirements as top-level domain servers.
5. Running the reverse server for class C blocks does not imply
that one controls that part of the reverse domain, it only im-
plies that one administers that part of the reverse domain.
6. Before adding individual nets, the administrator of a reverse
domain must check wether all servers to be added for these nets
are indeed setup properly.
7. There are some serious implications when a customer of a ser-
vice provider that uses address space out of the service provider
class C blocks, moves to another service provider. The previous
service provider cannot force its ex-customer to change network
addresses, and will have to continue to provide the appropriate
delegation records for reverse mapping of these addresses, even
though it they are no longer belonging to a customer.
8. The registration of the reverse zones for individual class C
networks will usually be done by the registry administering the
class C block this network has been assigned from. The registry
will make the necessary changes to the zone, and update the net-
work objects in the RIPE database for these networks, to reflect
the correct "rev-srv" fields. In case the RIPE NCC receives a
request for the reverse zone of an individual class C network out
of a block that has been delegated, the request will be forwarded
to the zone contact for this reverse block.
9. The NCC advises the following timers and counters for direct
subdomains of 193.in-addr.arpa: 8 hours refresh (28800 seconds),
2 hours retry (7200 seconds), 7 days expire (604800 seconds) and
1 day Time To Live (86400 seconds). The retry counter should be
lowered where connectivity is unstable.
Above procedures are defined to ensure the necessary high availa-
bility for the 193 reverse domains, and to minimize confusion.
The NCC will ensure fast repsonse times for addition requests,
and will in principle update the 193.in-addr.arpa domain at least
once per working day.

Procedures for the delegation of individual network zones by the
RIPE NCC.
The registration of the reverse zones for individual class C net-
works will usually be done by the registry administering the
class C block this network has been assigned from. In case the
zone corresponding to the class C block has not been delegated,
the RIPE NCC will automatically add the reverse nameserver as
specified in the "rev-srv" attribute of the RIPE database object
for this network, using the following procedures:
1. Because of the increasing importance of correct reverse ad-
dress mapping, for all delegated networks a good set of secon-
daries must be defined. There should be at least two nameservers
for all networks delegated.
2. The "rev-srv" field should ONLY contain one fully qualified
domain name of a nameserver which is authoritative for the re-
verse zone for this network.
3. If a network has or is going to have any external connectivi-
ty, it is strongly recommended that it has at least one reverse
nameserver that can be reached from all of the Internet.
4. The checking and addition of the reverse zones for single net-
works is completely automated at the RIPE NCC. Although we do
our best to check the setup of the nameservers, these does not
receive the same level of scrutiny as nameservers for blocks of
class C network numbers. It is the responsibility of the network
contacts to ensure proper operation.
5. Any problems regarding the reverse zones in 193.in-addr.arpa
should be directed to <[email protected]>.
The NCC also suggests that similar procedures are set up for the
delegation of reverse zones for individual class C networks from
the registries to individual organisations.
