The assignment of PI address space is part of the service that the RIPE
NCC provides to its members. This means that there are no extra costs
involved in getting PI address ranges for your customers.

It is difficult (and not our role) to judge if PI address space is the
best solution for your customer, anyway here are a few points to be aware
- Assignments of address space are valid as long as the criteria for
the original assignment are still met, independently of the use of a
particular provider's services.
(This means that if the customer leaves you they can bring the address
space with them)
- Assignment of address space does NOT imply that this address space will
be ROUTABLE ON ANY PART OF THE INTERNET;
- The policy does not allow sub-assignments of address space from
"ASSIGNED PI" blocks.
n.b. If they are providing connectivity to their customers via this address
space, then this is not an assignment to them, since you are using the
adresses to provide connectivity. The policy allows up to a /30 for this

In order to get PI address space from the RIPE NCC you need to fill in a
"European IP Address Space Request Form" as you do for PA assignment
requests, the only differences are the following points:
- 1) In the #[REQUEST OVERVIEW TEMPLATE]# enter "YES" at the the
- 2) Once you have sent the request to hostmaster@localhost you will
receive an automatic reply from the hm-robot, containing 3
questions (see below). Once you have answered the 3 questions we
will evaluate your request as usual.
If your customer will need to assign address space to their customers, or
they will expand their activities in the future, they could think about
becoming a LIR.

If you have any further question don't hesitate to contact us within
1. Why is PI space required rather than PA space?
- If PI is requested for multi-homing please explain why the
second provider cannot route PA space as a more specific
route(with the PA block holder adding a more specific route
- The same policies apply to PI space as PA. Administrative ease
and/or routing are not reasons for PI. Please read the information
about PA/PI from the RIPE Document, IPv4 Address Allocation and
Assignment Policies in the RIPE NCC Service Region, Sections 5.1.5
- Also to bear in mind :
The RIPE NCC will not allocate PI.
Future assignments of PI space are unlikely to be contiguous
with the addresses assigned for this request.
The RIPE NCC cannot guarantee the routability of any address
space it issues.
- If you will have end-users with their own networks, PA space
should be assigned by an LIR.
2. Please check you are not requesting for extra address space for
routing or administrative reasons. See Section 5.2 "Assignment
Guidelines", of the IPv4 Address Allocation and Assignment Policies
in the RIPE NCC Service Region,
"As conservation and aggregation are often conflicting goals,
each address request needs to be evaluated carefully in order
to assign the amount of address space fulfilling these goals
in the best way possible. Implications for both conservation
and aggregation have to be evaluated before an assignment is
made. For example, if the assignment of the exact number of
addresses required creates a large number of prefixes, it
might be better to assign one single prefix. In other cases,
multiple prefixes might have to be "announced" if the
assignment of one single prefix would leave too many
3. Please confirm whether you have made the end-user aware of the
warning given in "Provider Independent vs Provider Aggregatable
Address Space", Section 3, "Detailed Recommendations":
Assignment of this address space is valid as long as the
criteria for the original assignment are still met. However,
assignment of address space does NOT imply that this address
space will be ROUTABLE ON ANY PART OF THE INTERNET. It is
expected that users will have to pay a premium for actual
routing of PI addresses as opposed to PA addresses. It may
eventually become impossible to get relatively small amounts
of PI space routed on most of the Internet. We strongly suggest
you contact any prospective service provider for information
about the possibility and pricing of service when using PI
You are required to confirm that the points mentioned above have
been read and confirmed and that your customer requesting the PI
Address Space is fully aware of the disadvantages with Provider
