The IETF 116 network connects to the Internet via two 10Gb/s uplinks donated by NTT and KDDI. The IETF uses 2001:67c:370::/48 and 2001:67c:1230::/46 for IPv6 and 188.8.131.52/18 and 184.108.40.206/20 for IPv4. We supply bandwidth for the conference space and venue hotel guest rooms.
Intercontinental Guest Room and Public Space WiFi
The IETF network covers the guest rooms and 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.
While we are using the IETF meeting network for Internet connectivity, we are using the hotel's access 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 email support @ ietf.org, and we are glad to help!
Meeting Room Wireless at Pacifico North
WiFi (802.11 a/g/n/ac/ax) is provided throughout the venue on 2.4 and 5GHz bands with IPv4 and IPv6.
Most users should choose the 'ietf' SSID:
Here’s a quick summary of the available WiFi networks:
|ietf||The default network||yes||5Ghz only||v4 and v6|
|ietf-legacy116||For legacy and unencrypted use||no||2.4 and 5Ghz||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/WPA3 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.
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.
A Note For Android Users
Here are the relevant settings for connecting Android devices to the secure ietf networks.
- Network name (e.g. ietf): ietf
- Security: WPA/WPA2-Enterprise
- EAP Method: PEAP
- Phase 2 authentication: MSCHAPv2
- CA Certificate: Use system certificates
- Do not verify
- Domain: services.meeting.ietf.org
- Identity: ietf
- Password: ietf
The Terminal Room is located in G416. The Terminal Room is open 8:30-19:00 beginning Sunday, March 26, 2023, at 16:00 and ending on Friday, March 31, 2023, at 15:00. The room consists of table seats, wired access, and 100V 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 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 and will be staffed during the following hours:
|Sunday||16:00 - 19:00|
|Monday||8:30 - 17:00|
|Tuesday||8:30 - 17:00|
|Wednesday||8:30 - 17:00|
|Thursday||8:30 - 17:00|
|Friday||8:30 - 15:00|

A printer at the Network Help Desk is available to all IETF users. The printer is an Epson EW-M530F and is accessible via LPD, Bonjour, and standard TCP/IP on port 9100. The hostname for it is ietf116-printer.meeting.ietf.org.
|Name||Model||Capabilities||IPv4 Address||IPv6 Address||Notes||Drivers|
|ietf116-printer.meeting.ietf.org||Epson EW-M530F||Inkjet w/Duplexer||220.127.116.11||2001:67c:370:160::18||Bonjour name: ietf116-printer||Printer Drivers|
Instructions for macOS using Bonjour auto-setup (DNS-Based Service Discovery)
(Note that this method is unavailable if you have configured an explicit DNS search list. Please see below for the manual configuration instructions.
- Open System Preferences -> Printers & Scanners -> "+" below printer list
- Select the "Printer" icon at the top of the window
- You should see the printers discovered by Bonjour. Pick the right one.
- Enjoy hassle-free printing.
Instructions for macOS using manual configuration
- Open System Preferences -> Printers & Scanners -> "+" below printer list
- Select the "Globe" icon at the top of the window
- Enter "ietf116-printer.meeting.ietf.org" in the Address field.
- Select "Airprint" from the Protocol field drop-down menu
- Leave the Queue field blank.
- Click Add
Instructions for Windows
- Download and install the appropriate driver from: https://www.epson.jp/support/portal/download/ew-m530f.htm
- If you have difficulty installing the printer for ietf116, please visit the Network Help Desk adjacent to the IETF Registration Desk on the Lobby Level.
- Email the document or file you wish to print as an attachment to ietf116 @ print.epsonconnect.com
- Retrieve your printout from the printer near the Network Help Desk in the Registration Area.
The following network services are provided:
|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:
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 on the IETF network need to be approved by the IETF Chair. For IETF 116, no network experiments were requested.
The terminal room and IETF network are made possible by our sponsors' contributions and our volunteer team's efforts. If you see them in the halls, be sure to thank them for their work!
