RIPE 48 Network Connectivity

Remember to bring your wireless card to the RIPE Meeting!

Connectivity

The connectivity to the Hotel is provided by Global Voice Networks.

The network will be up and running from Monday May 3, 08:00 until Friday May 7, 13:00.
Due to the General Meeting on Friday afternoon we will have wireless in the St.Johns II and the registration areas for a prolonged period.

We will have router filters in place. No longer due to the limited bandwidth, but because of proper networketiquette (RFC1918).
If you have any connection difficulties, do not hesitate to come to the registration desk.

Only possible onsite: current traffic information during the RIPE Meeting and from the RIPE Meeting address space.

Terminal Room

The conference site has a Terminal Room with 20 PCs, a printer and a number of laptop drops. You can get a patch cable to connect to an available switch at the registration desk. The room will also have 802.11b wireless connectivity.

The Terminal Room is in the Foyer Room and will be open at the following times:

Grand Ballroom / Plenary Room

The Grand Ballroom will be equipped with wireless connectivity.

All wireless addresses for the RIPE Meeting are in the 193.0.8.0/23 block.

Please read our note about wireless security.

The Krasnapolsky Hotel provides wireless connectivity in the bar and the foyer. If you want to use the hotel's wireless connectivity, you will have to pay for this service. To make sure you are not using their wireless connectivity configure this network name:

    Global Settings:
	           IEEE Name/ESSID: ripemtg

RIPE NCC will be providing a limited number of wireless cards for loan to attendees during the RIPE Meeting. Cards will be available on a first-come, first-served basis at the Registration Desk from Monday on. There will be connectivity for people with:

802.11b Compliant, Direct Sequence Spread Spectrum 2.4 GHz (DS) cards
    (11 Mb/s)

• We will take a credit card number to ensure timely return of your card.
• On Friday (or earlier if you wish), please return the cards to the Registration Desk .
  In the unfortunate event that you lose or break the wireless card, your credit card will be charged EUR 250.

Wireless Specifications

If you already own a wireless card, please feel free to bring it. If you are looking to buy a wireless card, you should probably get any brand of card that offers IEEE 802.11b compliancy. You'll probably want to get a card that uses Direct Sequence (DS) technology, as frequency hopping is not compatible with DS transmissions.

Drivers

Drivers can be downloaded from:

• Avaya for windows and linux
• Aironet
• Lucent WaveLAN
• Cabletron
• Various flavours of UNIX:

Squid Cache

Take advantage of the RIPE Web cache! In addition to saving bandwidth, caching reduces the load on the Web sites you're accessing, and gives you lower latency to overseas hosts.

Follow these steps to configure your browser to use the cache.

• Netscape users:
  • Select Edit from the main menu bar
  • Select Preferences....
  • In the preferences window, click on the small triangle next to Advanced
  • Select Proxies
  • Select the Automatic proxy configuration option
  • Enter the following host name: proxy.ripemtg.ripe.net
• Explorer users:
  • Select View on the main menu bar
  • Select Internet Options at the bottom
  • Select the Connection tab
  • Select Configure... in the Automatic Configuration sub-window
  • Enter the following host name: proxy.ripemtg.ripe.net

The RIPE 48 cache uses Squid, a freely available Web proxy cache.

IPv6

All RIPE (wireless and wired) Ethernet ports will be IPv4/IPv6-ready. The RIPE Meeting site will have connectivity to the IPv6 network via a tunnel to RIPE NCC office. Our provider is SURFnet. You'll want to use IPv6 stateless address autoconfiguration (RFC 2462). We do not provide static IPv6 addresses. The address space we will use is 2001:610:241::/64.

Please, do not run router advertisments on the Meeting network

IPv6 implementations for various laptop platforms are available from ipv6.org.

DHCP

We will again run Dynamic DNS updates.

Only possible onsite: information from the RIPE DHCP server during the RIPE Meeting and from RIPE Meeting address space only.
The first graph shows the number of IP addresses assigned and the number of MAC addresses making DHCP requests.
The second graph shows the rate at which addresses are assigned.

Static addresses

If you need static addresses you will find RFC 2322 compliant clothpegs at the Terminal Room near the printer.
