External Connectivity
The IETF 124 network connects to the Internet with 2x10Gb/s donated by TELUS and 1x10GB/s via Beanfield to Metro Optic for Global Transit.
The IETF uses the following network prefixes:
- 2001:67c:370::/48
- 2001:67c:1230::/46
- 31.133.128.0/18
- 31.130.224.0/20
The IETF NOC supplies connectivity for the conference space and the venue hotel.
Guest Room and Hotel Public Space WiFi
The IETF network covers the guest rooms and the public spaces throughout the Fairmont using the 'ietf-hotel' and NEW FOR IEFT 124 uses a password of ietfietf. If you have performance issues with this network, please let us know.
It's important to note that while the IETF meeting network provides internet connectivity, guest rooms and public spaces are covered by the hotel's access points. As such, there may be limitations to the extent of improvements we can make. If you experience any issues with the 'ietf-hotel' SSID, you can contact our Help Desk or email support@ietf.org, and we will be happy to assist you.
Meeting Room Wireless at the Fairmont
New for IETF 124
After conducting a successful internal experiment in Madrid with new wireless hardware donated by Cisco, we are deploying over 70 new Cisco 9176 access points in the Fairmont meeting space, which support Wi-Fi 7 on the ietf SSID.
WiFi (802.11 a/g/n/ac/ax/be) depending on the SSID is provided throughout the Meetings Room on 5GHz and New at 124 6GHz bands, with IPv4 and IPv6.
The IETF meeting WiFi is WPA3 or WPA2 PSK. We have been using WPA3 with a fallback to WPA2 for many past meetings. New for 124 The SSID ietf is now WPA3 only. If your devices can not support WPA3 please use ietf-dual-stack that is WPA2 only.
The default network (SSID “ietf”) will allow your device to signal a preference for IPv6-only operation while still supporting IPv4 if needed via translation mechanisms by implementing the “IPv6-Only Preferred Option” [RFC 8925]. This builds on the trials during IETF 122 Bangkok, and IETF 121 Dublin and put in place and put in to production at IETF 123 in Madrid. For more information see:
https://www.ietf.org/blog/ietf-ipv6-mostly-meeting-network
Most users should choose the 'ietf' SSID:
password: ietfietf
If you are not able to connect use 'ietf-dual-stack'
password: ietfietf
Here’s a quick summary of the available WiFi networks:
| SSID | Description | Frequencies | IP Versions | WPA |
|---|---|---|---|---|
| ietf | IPv6-Only Preferred with Option for DHCPv4 [RFC 8925] | 5Ghz and 6GHz | v6 - NAT64 - v4 | WPA3 |
| ietf-dual-stack | Dual-stack provides both globally routable IPv4 and IPv6 addresses | 5Ghz only | v4 - v6 | WPA2 |
| eduroam | Educational users | 2.4 and 5Ghz | v4 - v6 | WPA2 |
The WiFi network implements two BCP38-like filters:
- Packets from manually configured IPv4 addresses that are not assigned by DHCP are dropped. DHCP packets are snooped by our wireless LAN controllers to perform this filtering.
- Packets from IPv4 and IPv6 addresses that cannot be resolved via ARP/ND are filtered out. Proxy ARP/ND is performed by our wireless LAN controllers for this filtering.
Shared Workspace
The Shared Workspace is located in Rue Sherbrooke and Rue Mansfield. The Shared Workspace is open 8:00-19:00 beginning Sunday at 16:00 and ending on Friday, at 15:00. The room consists of table seats, wired access, and 110V power ports.
When using the Ethernet connections in the Shared Workspace, IPv4 addresses are provided by DHCP. Please use Stateless Auto-configuration for IPv6 (SLAAC). A DHCPv6 server or RDNSS will provide network information.
Help Desk
IT support is being provided next to the Registration Desk and will be staffed during the following hours:
| Day | Hours |
|---|---|
| Monday | 8:30 - 17:00 |
| Tuesday | 8:30 - 17:00 |

NOC and Ticketing
To communicate with the NOC staff, send an email to support@ietf.org with as much detail regarding your issue and configuration as possible.
Please provide the following information:
- MAC Address
- Current Location
- Device type and operating system
- Description of the issue
This information will expedite ticket processing. If you're on-site and need direct network assistance (i.e., you have no network), please go to the Help Desk.
The Secretariat has a ticket system to report problems with the meetings. Please send mail to: support@ietf.org to request help. The Secretariat is responsible for helping with the following:
- A/V in meeting rooms
- Beverage and food
- Zulip (chat)
- Projectors
- Room temperature (too hot/cold)

Geolocation
There is a geolocation feed published here: https://noc.ietf.org/geo/google.csv
Geolocation service for event networks is often incorrect. Suggestions and assistance are welcomed. You can also try searching via https://www.google.com/ncr (no country re-direct).
Experiments
Experiments on the IETF network need to be approved by the IETF Chair.
For IETF 124, no network experiments were requested.
Thanks
The IETF network is made possible by our dedicated volunteer team, some of whom have the support of their employers. If you see any of these amazing volunteers in the halls, please be sure to thank them for their hard work and commitment!
