NI&S does not currently manage allocation of IPv6 addresses; most hosts will by default automatically configure one or more IPv6 addresses using StateLess Address AutoConfiguration (SLAAC). However, should users wish to assign static IPv6 addresses, we have tools to assist Network Liaisons (NLs) in allocating them to avoid collision with other users.
The hostmaster will assign your department an Organizationally Unique Identifier (OUI) which can be used in your IPv6 addresses. When you request an OUI, you will also be sent a list of randomly generated host suffixes with that OUI, that you can use on any subnet on-campus. More info on OUIs can be found in the Network Liason handbook and Hostmaster FAQ.
IPv6 Prefix Delegation
- NI&S will assign and route whole IPv6 prefixes (typically /60 or /64) on request. Submit a 4help ticket to the Network Engineering group.
- This service is still evolving.
- In the future, we will use DHCPv6 Prefix Delegation for ordinary use cases.
IPv6 DHCP (DHCPv6)
- NI&S provide minimal DHCPv6 services at this time. This service strictly exists to inform client devices of DNS servers and NTP servers on the network. Many clients will prefer this information over the equivalent information provided in Router Advertisements (RAs). Addresses are not allocated via DHCPv6 at this time.
- Some ill-behaved IPv6-capable clients will only use addresses from DHCPv6. We recommend contacting your vendor and asking they implement SLAAC. We may configure DHCPv6 for address assignment on a case-by-case basis.
IPv6-only hosts
- NAT64 is not a service we offer at this time. If you see 64:ff9b::/96 addresses in DNS, you should check your DNS configuration.
