I don't know how to use those ULA things, I need a howto for dummies somewhere.
And I have to find out if that thing interferes with Telefónica own setup. They reserve for themselves a portion of the IPv4 DHCP addresses, for instance.
Take a look on page 53 of the English manual. There's a checkbox for Enable ULA Prefix Advertisement. Enable that and Random Generate. That should generate a ULA prefix on your network, in addition to your global prefix. ULA is the IPv6 version of IPv4 RFC1918 addresses and will not interfere with anything your ISP provides.
Ok, it generates a random prefix. Who generates the "posfix" on each machine?
Do they still get the global addresses?
Ok, I enabled it. I get: 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:d8:61:a1:5a:bd brd ff:ff:ff:ff:ff:ff altname enp34s0 inet 192.168.1.14/16 brd 192.168.255.255 scope global eth0 valid_lft forever preferred_lft forever inet6 fd81:a:b:0:9e5c:300d:c313:5004/64 scope global temporary dynamic valid_lft 604741sec preferred_lft 86002sec inet6 fd81:a:b:0:2d8:MAC/64 scope global dynamic mngtmpaddr <==== valid_lft forever preferred_lft forever inet6 2a02:A:B:0:8cfd:1160:9abb:a5e3/64 scope global temporary dynamic valid_lft 86394sec preferred_lft 1908sec inet6 2a02:A:B:0:bdf0:c597:538c:ccb7/64 scope global temporary deprecated dynamic valid_lft 86394sec preferred_lft 0sec inet6 2a02:A:B:0:634a:1bd5:5b95:13b6/64 scope global temporary deprecated dynamic valid_lft 86394sec preferred_lft 0sec inet6 2a02:A:B:0:2d8:MAC/64 scope global dynamic mngtmpaddr valid_lft 86394sec preferred_lft 86394sec inet6 fe80::2d8:MAC/64 scope link valid_lft forever preferred_lft forever ...
I don't see the advantage for accessing local machines on IPv6 by name, intranet only. I already can access the local machines by name on IPv4, thus IPv6 offers no advantage.
