networking - Does the idea of private ip address in ipv6? -

-

for idea of private, mean 10.*.*.* idea of ipv4. seems ipv6 don't conserve ip addresses these more.

so, if want create private subnet don't want others know subnet number or access subnet ip address. can create own range of ip subnet number, seems in way, conflicts global ip address.

i know idea of link local address, think that's useless when want several links constitute network.

if setting private local network development/testing , don't have actual ipv6 connectivity of own (or isp stupid , gave /64) unique local addresses work fine you.

however, unique local addresses cannot used connectivity global internet. if need this, should global addresses , proper firewall (as nat not needed , discouraged in ipv6).

to /48 ula prefix, visit this generator , throw in mac address. (using mac address generate prefix specified rfc 4193, defines unique local addresses.)
