The IETF 115 network connects to the Internet via two 10Gb/s uplinks. The first is donated by Comcast direct via EDI. The second is Comcast EPL for transport to the IX; Netrality providing cross-connect to Hurricane Electric for connectivity. The IETF uses 2001:67c:370::/48 and 2001:67c:1230::/46 for IPv6 and 31.133.128.0/18 and 31.130.224.0/20 for IPv4. We supply bandwidth for the conference space and venue hotel guest rooms.
The IETF network covers the guest rooms and limited coverage in the public spaces throughout the hotel using the 'ietf-hotel' SSID. If you have performance issues with this network, please let us know.
We are seeing significant signal bleed of the 'ietf-hotel' SSID into the meeting space. When you are in the meeting rooms, please make sure you aren't still associated to the guest room network.
While we are using the IETF meeting network for Internet connectivity, we are using the hotel's acccess points to cover the guest rooms and public spaces, so there are limits to the improvements we can make.
If you have trouble with the 'ietf-hotel' SSID, please contact the Help Desk or send email to support @ ietf.org and we are glad to help!
WiFi (802.11 a/g/n/ac) is provided throughout the venue on 2.4 and 5 GHz bands with IPv4 and IPv6.
Most users should choose the 'ietf' SSID:
user: ietf
password: ietf
Here’s a quick summary of the available WiFi networks:
| SSID | Description | Encrypted | Frequencies | IP Versions |
|---|---|---|---|---|
| ietf | The default network | yes | 5Ghz only | v4 and v6 |
| ietf-legacy115 | For legacy and unencrypted use | no | 2.4 and 5Ghz | v4 and v6 |
| ietf-2.4ONLY | An encrypted network for 2.4Ghz users | yes | 2.4Ghz only | v4 and v6 |
| ietf-v6ONLY | IPv6 only | yes | 5Ghz only | v6 only |
| ietf-nat64 | IPv6 stack with NAT64 to access IPv4 resources | yes | 5Ghz only | v6 with NAT64 & DNS64 |
| ietf-nat64-unencrypted | IPv6 stack with NAT64 to access IPv4 resources | no | 2.4 and 5Ghz | v6 with NAT64 & DNS64 |
| eduroam | Educational users | yes | 2.4 and 5Ghz | v4 and v6 |
All networks marked as encrypted provide layer 2 security. They use WPA2 Enterprise with 802.1X (PEAP or TTLS) authentication and AES encryption. Although all users are using the same credentials (user 'ietf', password 'ietf'), each user gets unique session encryption keys. The certificate for services.meeting.ietf.org is signed by Starfield Technologies, Inc., with the following fingerprint.
| hash f(x) | fingerprint |
|---|---|
| SHA1 | DB:2A:E7:D1:AF:B5:5A:03:43:11:BC:B0:AD:77:E9:D1:D7:12:A7:25 |
| SHA256 | 8A:AC:ED:35:86:7F:FC:35:C2:82:33:AA:E4:6A:CA:C5:8E:97:20:9C:6D:73:82:9E:CB:26:77:D6:A4:72:A9:C5 |
The WiFi network implements two BCP38-like filters:
Here are the relevant settings for connecting Android devices to the secure ietf networks.
Connecting to the 'ietf' SSID on Windows 7 requires a few extra steps. If you're struggling to get connected to an encrypted SSID on your Windows laptop, please come by the Network Help Desk. Alternatively, you can try yourself; instructions are here
The Terminal Room is located in Salon 10. The Terminal Room is open 24 hours each day beginning Sunday, July 23rd, 2022 at 16:00 and ending on Friday, July 29th, 2022 at 15:00. The room itself consists tables seats, providing some wired access and 110V 60 Hz Type A power ports.
The terminal room has no terminals, PCs, or other user-accessible machines. It is simply a place to get power, wired and WiFi Internet access, and/or work quietly.
When using the Ethernet connections in the Terminal Room, IPv4 addresses are provided by DHCP. Please use Stateless Auto-configuration for IPv6 (SLAAC). A DHCPv6 server or RDNSS will provide network information.
Please note that at the request of the IETF Chair, demonstrations are no longer permitted in the Terminal Room.
IT support is being provided next to the Registration Desk on the BR level, and will be staffed the following hours:
| Day | Hours |
|---|---|
| Sunday | 16:00 - 19:00 |
| Monday | 8:00 - 17:00 |
| Tuesday | 8:00 - 17:00 |
| Wednesday | 8:00 - 17:00 |
| Thursday | 8:00 - 17:00 |
| Friday | 8:00 - 15:00 |
There are several ways 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:
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:
There is a printer at the Network Help Desk and is available to all IETF users. The printer is an Epson WF-3820 and is accessible via LPD, Bonjour, standard TCP/IP on port 9100. The hostname for it is ietf115-printer.meeting.ietf.org.
| Name | Model | Capabilities | IPv4 Address | IPv6 Address | Notes | Drivers |
|---|---|---|---|---|---|---|
| ietf115-printer.meeting.ietf.org | [Epson WF-3820] | Inkjet w/Duplexer | 31.133.160.18 | 2001:67c:370:160::18 | Bonjour name: ietf115-printer | Printer Drivers |
(Note that this method is not available if you have configured an explicit DNS search list. Please see below for the manual configuration instructions.
The following network services are provided:
| Service | Address | Notes |
|---|---|---|
| NTP | ntp.meeting.ietf.org | A stratum 2 time service is provided via IPv4 and IPv6 unicast |
| DNS | ns1.meeting.ietf.org ns2.meeting.ietf.org | Validating recursive resolvers. The local domain is meeting.ietf.org. |
These services are being provided from both of the following servers:
| name | IPv4 | IPv6 |
|---|---|---|
| services-1.meeting.ietf.org | 32.31.130.229.6 | 2001:67c:370:229::6 |

There is a geolocation feed published here: https://noc.ietf.org/geo/google.csv
Geolocation service for event networks is hit or miss. Suggestions/assistance is welcomed. You can also try searching via https://www.google.com/ncr (no country re-direct).
Experiments on the IETF network need to be approved by the IETF Chair. For IETF 115, no network experiments requested.
The terminal room and IETF network are made possible by contributions from our sponsors and the efforts of our volunteer team. If you see them in the halls, be sure to thank them for their work!
