External Connectivity
The IETF 122 network connects to the Internet using two 1Gb/s donated by True and Symphony and corridinated with BKNIX.
- 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 Marriott using the 'ietf-hotel' SSID. 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 Marriott
WiFi (802.11 a/g/n/ac/ax) is provided throughout the Marriott on 5GHz bands with IPv4 and IPv6.
The IETF meeting WiFi is WPA3 PSK with a fallback to WPA2. While we'd like to be able to only do WPA3, we've discovered that many devices don't yet support it, so we currently are using Transition mode (fallback to WPA2).
Most users should choose the 'ietf' SSID:
password: ietfietf
Here’s a quick summary of the available WiFi networks:
| SSID | Description | Frequencies | IP Versions |
|---|---|---|---|
| ietf | The default network | 5Ghz only | v4 and v6 |
| ietf-ipv6-mostly | IPv6-Only Preferred with Option for DHCPv4 [RFC 8925] | 5Ghz only | v6 |
| eduroam | Educational users | 2.4 and 5Ghz | v4 and v6 |
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 Pavilion 1/2. 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 220V 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.

IT support is being provided next to the Registration Desk and will be staffed during the following hours:
| Day | Hours |

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 122, 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!
