IETF 82 Network Information (draft) - Taipei, Taiwan

Terminal Room

The Terminal Room is located in V.I.P room on the 4 Level of the TICC and is open 24 hours a day beginning at 8:30am on Sunday, November 13th and ending at 12:30pm on Friday, November 18th. A help desk is being provided, hours are listed below. The room itself consists of approximately 74 seats providing some wired access and 110v North American power ports. There are also two printers available, both duplex: one color, one black&white. Please note that this terminal room has, in fact, 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. To cut down on the mess, ethernet cables have not been installed to every seat in the Terminal Room.

  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 on the 4F in V.I.P. room.

Network Basics

External Connectivity

The IETF 82 network connects to the Internet via two 1Gb/s links, provided by Chunghwa Telecom. The entire event is addressed out of the block for IPv4 and 2001:df8::/32 for IPv6. IPv6 is native and is supported on both links. There is a 100Mb link to connect the Taipei International Convention Center to the the Grand Hyatt Taipei. This bandwidth will be used to deliver the IETF network to the wired internet connections on several floors of the Hyatt.

Meeting Room Wireless

An 802.11 a/b/g/n wireless network is being provided liberally throughout the venue hotel. 802.11n is only available on the 5Ghz frequencies.

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

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

To use 802.1X:

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

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.

Experimental Networks

There are two experimental SSIDs. "ietf-v6ONLY" is there to demonstrate the current state of an IPv6 only Internet. Do not expect any services to be available via IPv4 on this SSID.

SSID Access Credentials Purpose
ietf-v6ONLY None A IPv6-only network for investigating IPv6 in the absence of IPv4
eduroam Your eduroam credentials An instance of the eduroam project. See eduroam website

Guest Room Access

The IETF network will be available in the Hyatt from Sunday, November 13 through Friday November 18 in the following areas:

Guest room wired internet access: The IETF network will be limited to a certain number of floors at the Hyatt.

If you made your reservation in the IETF block your room will be on a specified floor with wired IETF network access. IETF attendees with reservations at the Hyatt outside of the IETF room block may request their room be on one of the floors access to the IETF network and the Hyatt will do their best to accommodate the request. Wireless in all guest rooms will remain on the Hyatt Hotel network, however, the hotel is increasing their available bandwidth to meet the expected increase in usage.

Public area wireless: The lobby, restaurants, and clubs on floors 1, 2, and 3 of the Hyatt will have IETF wireless access in most locations. This will include the full set of IETF SSIDs and services, including IPv6. Note that the Hyatt Hotel wireless will also be available in these areas.

This access is being provided thanks to the cooperation of the Hyatt and the hard work of the network team.


There is a printer in the Terminal Room and is available to all IETF users. The printers are RICOH MP2000L and RICOH SP C420DN.

The terminal room and IETF network are made possible by the generous contributions by a number of companies and by the tireless efforts of our volunteer team. If you see any of these people in the halls, please be sure to thank them for all their work!
