My home machine has two IPv6 address, that look like this (obfuscated for security sake):
2: enp1s0 inet6 2500:1600:4650:bc59::49/128 scope global dynamic noprefixroute \ valid_lft 1127515sec preferred_lft 1127515sec 2: enp1s0 inet6 2500:1600:4650:bc59:1440:adb5:bacb:4447/64 scope global dynamic noprefixroute \ valid_lft 1209597sec preferred_lft 1209597sec 2: enp1s0 inet6 fe80::a42a:340c:d982:163c/64 scope link noprefixroute \ valid_lft forever preferred_lft forever
I get that the last one (fe80) is a link-local address, but the other two- I'm not sure why I have both. My system is a Pi-Hole server, and thus it's a DHCPv6 server (SLAAC+RA turned on).
Could you explain the 2 addresses? I guess the /64 is my host's real IP?
