IETF 92 Network Information – Dallas, Texas, US

NEEDS UPDATING! - Lucy - (some editing done...)

Flash: Some users are having problems using Intel Centrino cards and the IETF network. Please see:

Terminal Room

The Terminal Room is located in the Brasserie, which is directly behind the Registration desk on the Lobby Level. The Terminal Room is open 24 hours a day beginning Sunday, 22 March, 2015 at 16:00 and ending on Friday, 27 March, 2015 at 15:00. A help desk is being provided, hours are listed below. The room itself consists of approximately 100 seats, providing some wired access and 110v power ports. There is also an HP Officejet Pro 8610 (N911a) printer available.

Please note that this terminal room has no terminals, PCs, or other user-accessible machines. It is simply a place to get power, wired Internet access, help desk support, or print documents.

When using the Ethernet connections in the Terminal Room, IPv4 addressing is provided via DHCP. Please use Dynamic Auto-configuration for IPv6. A stateless DHCPv6 server or RDNSS will provide network information. To cut down on the mess, ethernet cables have not been installed to every seat in the Terminal Room. If you need a cable, please ask at the Help Desk.

Please note that at the request of the IETF Chair, demonstrations are no longer permitted in the Terminal Room.

Help Desk

A help desk is being provided and will be staffed the following hours:

Sunday 16:00 to 19:00
Monday 8:00 to 20:00
Tuesday 8:00 to 20:00
Wednesday 8:00 to 20:00
Thursday 8:00 to 20:00
Friday 8:00 to 16:00

NOC and Ticketing

There are several ways to communicate with the NOC staff.

  1. Submit a new trouble ticket via the trac web interface. Filling in the following fields: "My MAC Address", "My Current Location", and "My OS" may expedite ticket processing. If you have an existing account on you can use your established credentials (email address and tools password) to log in.
  2. Send an email to with as much detail regarding your issue and configuration as possible.
  3. If you're on site and need direct network assistance (i.e - you have no network) please go to the helpdesk, which is located in the Terminal Room.
  4. Use the Jabber room at noc @ to report issues or communicate with the NOC.

You can also use trac to review outstanding tickets before reporting an issue or to update outstanding tickets.

Network Basics

External Connectivity

The IETF 92 network connects to the Internet via two 1Gb/s links provided by Time Warner Cable. The IETF uses, and for IPv4 and 2001:67c:1230::/46, 2001:67c:370::/48 and 2001:df8::/32 for IPv6. We are supplying bandwidth for the conference space, as well as wireless and wired connections in the guest rooms.

Meeting Room Wireless

An 802.11 a/g/n/ac wireless network is being provided liberally throughout the venue on both 2.4 and 5 GHz.

To use the meeting room wireless network, associate with the beaconed SSID of "ietf" for 802.11 a/g/n/ac and "ietf-a" for 802.11 a/n/ac. IPv4 addressing is provided via DHCP. IPv6 clients should use Dynamic Auto-configuration, and may use DHCPv6 or RDNSS to retrieve name server information.

For those interested in more link-layer security, WPA SSIDs with 802.1X is available. The SSIDs are "ietf.1x" and "ietf-a.1x". Do not use WPA-PSK as that will not work. Also, using TLS as an eap method is not advisable, please prefer TTLS or PEAP.

To use 802.1X:

  1. Associate to SSID: ietf.1x OR ietf-a.1x
  2. Use TTLS or PEAP/MSCHAPv2
  3. Do Not Verify Server Cert and we won't verify yours :)
  4. Username (case sensitive): ietf
  5. Password (case sensitive): ietf

If you have an eduroam account, we support authenticating via eduroam. Simply select the "eduroam" SSID. Use your eduroam credentials.

For a pure-IPv6 environment with no translation, use the ietf-v6ONLY SSID. If you'd like to try pure-IPv6 with NAT64 translation, try the "ietf-nat64" SSID.

Guest Room Access

The IETF Network is being extended to the guest rooms in the Fairmont. *Note* that while we are using the IETF meeting network for Internet connectivity, we are using the hotel's infrastructure (Ruckus access points) for the delivery to the guest rooms, so there are limits to the improvements we can effect. We recommend using the wired connection if you experience poor connectivity in your guest room.

Wired: IPv4 and IPv6 and provided via the wired connection in your room.


In the guest room areas you should find the “ietf-hotel” SSID. This network is 2.4Ghz only, and is being delivered via the Fairmont's Ruckus access points. We encourage heavy users and/or those having poor coverage to use the wired connection.


If you have trouble using any of the Public or Guest Room services, please try to switch to the hotel SSIDs or the hotel wired port. If that doesn’t work, please contact the Hilton support as listed in your room. If things are working fine on the hotel offerings but not on the IETF SSIDs/ports, please do contact us in the Terminal Room (South Pacific I) or via tickets @ and we’ll be glad to help!


There is a printer in the Terminal Room and is available to all IETF users. The printer is an HP Officejet Pro 8610 and is accessible via LPD, Bonjour, standard TCP/IP on port 9100. The hostname for it is
