Network Basics

The IETF 77 network is connected to the Internet via a 100M Fiber primary link and a backup 50M microwave link. The entire event is addressed out of the block for IPv4 and 2001:df8::/32 for IPv6. IPv6 connectivity is native over the primary fiber link, and tunneled to ISC on the backup.


An 802.11 a/b/g wireless network is being provided. Areas specifically covered are the meeting rooms and common areas on the 2nd, 3rd and 4th floors.
To use this network, associate with "ietf" SSID for 802.11a/b/g and "ietf-a-only" for 802.11a. Secure networks are also available with “ietf-sec” and “ietf-sec-a-only”.
The password for the secure network is ietf2010.
There is another unsecured SSID, with no IPv4 service available, for experimentation with IPv6. This SSID is " ietf-ipv6-only ".

The proper operation of the wireless network requires the assistance of all users. One of the most significant issues with wireless performance in past IETF meetings has been wireless clients automatically, or accidentally initiating "ad-hoc" networks that act as the official IETF wireless network, causing other users to associate with false IETF wireless networks. Therefore, please disable your client's ability to create an ad-hoc network and as well as the ability to automatically join an ad-hoc network. If you are using Windows XP or Mac OS X 10.4 and 10.5 to manage your wireless client, the instructions to disable creation of ad-hoc networks are listed below. If you are using other systems, please do whatever your particular wireless client management system requires to turn off ad-hoc networks.

Instructions for Mac OS X

  • Open System Preferences -> Network -> Airport -> Options
  • Un-check the box for "Create Computer-to-Computer networks".

Instructions for Windows XP

  • Open Properties -> wireless networks -> advanced
  • select "access point (infrastructure) networks only"
  • unselect "automatically connect to non-preferred networks".

Guest Room Access

Guests can get complimentary wireless access in their guestrooms by connecting to the “ietf” SSID.
When you connect to the wireless infrastructure using the SSID ietf you will be connected to the IETF network and will have all the capabilities of that network, including IPv6 access.
When you connect to the guestroom wired network you will not be using the IETF network at all. This means, in particular, you will not have IPv6 access.
