Technical Information


Three different networks are provided during RIPE 85: main network, nat64 network and legacy network. All networks share the same passphrase that is printed in your RIPE 85 badge booklet. The passphrase is also available throughout the meeting area.

Main network

This is the general network suitable for the most users. It is an IPv6-mostly network according to RFC 8925 supporting both dual-stack and IPv6-only operation. The network names are:

  • ripemtg (5 GHz, 802.11 ac compliant)
  • ripemtg-2.4-85 (2.4 GHz, 802.11 g/n compliant – use only in case your device cannot work on 5GHz band)

NAT64 network

An IPv6-only network with NAT64 is available for people willing to use IPv6-only mode despite their devices preferring dual-stack operation on the main network. The network names are:

  • ripemtg-nat64 (5 GHz, 802.11 ac compliant)
  • ripemtg-nat64-2.4-85 (2.4 GHz, 802.11 g/n compliant – use only in case your device cannot work on 5GHz band)

Legacy network

A legacy dual-stack network without support for IPv6-only operation is available as well. It can be used in need of native IPv4 despite the device preference of IPv6-only mode in the main network or to troubleshoot unforeseen issues in the main network. The network names are:

  • ripemtg-legacy-85 (5 GHz, 802.11 ac compliant)
  • ripemtg-legacy-2.4-85 (2.4 GHz, 802.11 g/n compliant – use only in case your device cannot work on 5 GHz band)


IPv4 addresses are assigned dynamically from the RIPE Meeting address space. IPv6 addresses are assigned using router advertisement (SLAAC). The list of DNS resolvers is provided by DHCPv6 and RDNSS.

Static Addresses

Please do not configure your own static IP address. If you need a static IP address, please go to the IT Support Desk.

Work Space

The lobby of the Metropol Hotel is available as a work space. A Lexmark CS510de printer is available at the registration desk:

Connectivity Problems

If you encounter any problems accessing the RIPE Meeting network, please email opsmtg [at] ripe [dot] net. To speed up the troubleshooting process, you can use this script on Mac OS X or Linux and send the results to the Technical Team for a quicker resolution.

Internet Connectivity and Network Information

Announcements about technical information and connectivity will be posted at the RIPE NCC Info Hub and online. You can report technical issues to the RIPE NCC Technical Crew or to staff at the IT Support Desk.
