Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko IPv6 te kaiwhaiwhai ki te IPv4. Ko te IPv6 te hua o te maha o nga tau o te whakamatautau me te korerorero i roto i nga momo tauira kawa i whakaarohia, penei i te TP / IX (RFC 1475), PIP (RFC 1621) me TUBA (TCP me UDP me nga Wāhitau Nui ake, RFC 1347). Ko tōna rerekētanga tino nui mai i te putanga 4 ko te rahi o ngā wāhitau. I te wā e whakamahi ana a IPv4 i ngā moka 32 mō te wāhitau, e tuku ana i te c. 4.3 piriona (4.3×109) wāhitau, IPv6 whakamahi wāhitau 128-bit whakarato ca. 340 undecillion, 3.4×1038 rānei ngā wāhitau. Ahakoa he puhoi te tango i te IPv6, mai i te Pipiri 2008, kua whakaatuhia e nga punaha kawanatanga katoa o te United States te tautoko hanganga taketake mo te IPv6.Ko te tohatoha o te kawa hou hei IPv6 kaore i te tino mohio tae noa ki te wa i whakaatuhia ai e IPv6 kaore ano kia whakamahia i mua. Ko etahi atu tono kawa i huaina ko IPv9 me IPv8 i puta mai mo te wa poto, engari kaore he hononga ki tetahi o nga paerewa paerewa o te ao, kaore hoki he tautoko. Heoi, i te Paenga-whāwhā 1, 1994, i whakaputaina e te IETF he kata mo te ra o Paenga-whāwhā e pā ana ki te IPv9.  Pātai: He aha te kaiwhakawhanake o te IPv4?
