I have a domain name that points toward my home server. Under every Ubuntu release up through Wily, by default I had a stable EIU-64 address that I could use for my AAAA record. However, after installing Xenial, I don't seem to get a stable address by default.
joejoe@myserver:~$ ip address 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:24:1d:d2:e3:f4 brd ff:ff:ff:ff:ff:ff inet 192.168.0.101/24 brd 192.168.0.255 scope global enp2s0 valid_lft forever preferred_lft forever inet6 2601:280:3068:2945:74ed:b303:6474:6e29/64 scope global temporary dynamic valid_lft 6965sec preferred_lft 3363sec inet6 2601:280:3068:2945:ac34:ea15:4340:29a4/64 scope global temporary deprecated dynamic valid_lft 6965sec preferred_lft 0sec inet6 2601:280:3068:2945:bdfd:6253:b07e:1308/64 scope global mngtmpaddr noprefixroute dynamic valid_lft 6965sec preferred_lft 6965sec inet6 fe80::dc3e:6127:bd4e:18b/64 scope link valid_lft forever preferred_lft forever
As you can see, all of the
inet6 addresses with
scope global have limited lifetimes. Is there a way to get my EIU-64 address back, or is there some other way to get a stable address that I can use in a domain name record?
