IPv6 addresses in the propagation display are inconsistently displayed - sometimes using '::' compression, sometimes not. For instance, with https://mrdns.com/propagation?name=wikipedia.org&type=AAAA https://mrdns.com/propagation?name=wikipedia.org&type=AAAA the same address is formatted as either '2620:0:861:ed1a::1' or '2620:0:861:ed1a:0:0:0:1'. The :: form is generally preferred.
