I te tau 2015, ko ARIN (te kawenga mō te rohe o Amerika Te Raki) te kai-rēhita, i pau katoa ai tana puna IPv4. Ā, i te marama o Whiringa-ā-rangi, i pau katoa hoki ngā wāhitau o RIPE, e tohatoha ana i ngā rauemi ki Ūropi me Āhia.

Te āhua i RIPE
I te tau 2012, RIPE mō te tīmatanga o te tohatoha o te poraka /8 whakamutunga. Mai i taua wā, 1024 noa iho ngā wāhitau i taea e ia kiritaki rehita te whiwhi, ā, nā tēnei i whakaroa ake te mimiti o te puna. Heoi, i te tau 2015, e 16 miriona ngā wāhitau IP kore utu a RIPE e toe ana; i te raumati o te tau 2019, i heke iho tēnei tau. .
I te mutunga o Noema, kua pakari , i kī ai kua tukuna e te kairēhita āna wāhitau IP whakamutunga, ā, kua pau āna rauemi. Mai i nāianei, ka whakakīia te puna mā ngā wāhitau ka whakahokia mai ki te tohatoha e ngā whakahaere maha. Ka tohatohahia ēnei i runga i te kaupapa tuatahi tae mai, tuatahi mahi i roto i ngā poraka /24.
Kei a wai tonu ngā wāhitau?
E toru atu ngā kai-rēhita kei a rātou tonu te IPv4, engari kua mahi rātou i roto i te "aratau whakaiti" mō ngā tau kua hipa. Hei tauira, kua whakauruhia e te AFRINIC o Āwherika he here mō te maha o ngā wāhitau kua tukuna me te arowhai pakari mō te whakamahinga e tika ana mō rātou. Ahakoa ēnei mahi, e matapaetia ana e ngā tohunga ko te IPv4 o te kai-rēhita o Āwherika i te marama o Poutū-te-rangi 2020 kē. Engari e whakapono ana ētahi ka tupu wawe atu tēnei – i te marama o Hānuere.
He iti noa ngā rauemi e toe ana i te Latin American LACNIC—kei te tohatoha i tana poraka whakamutunga /8. E ai ki ngā māngai o te whakahaere kei te tohatohahia e rātou te mōrahi o ngā wāhitau 1024 mō ia kamupene. Ko ngā kiritaki kāore anō kia whiwhi i ēnei i mua ka taea te aukati. Kua mahia ngā mahi rite e te Asian APNIC. Engari kei te wātea te whakahaere. ko te haurima anake o te puna kaukau /8, ka noho kau hoki i roto i ngā rā tata nei.
Kāore anō kia mutu
E kī ana ngā tohunga ka taea te whakaroa i te "roa o te ora" o te IPv4 mā te whakahoki i ngā wāhitau kāore i keremehia ki te puna tiritahi. Hei tauira, ko te kamupene hanga waka a Ford Motor Company me te kamupene inihua a Prudential Securities Neke atu i te 16 miriona ngā wāhitau IPv4 tūmatanui. I roto i tētahi miro i runga i ngā Pūrongo Hacker , kāore e hiahiatia ana e ēnei whakahaere te maha o ngā IP.
I tēnei wā, kaua e tukuna ngā wāhitau whakahoki i roto i ngā poraka, pērā i mua, engari i roto i ngā rahinga tino hiahiatia. Tētahi atu kainoho HN , kei te whakamahia kētia tēnei tikanga e ngā kaiwhakarato Spectrum/Charter me Verizon - ka tukuna e rātou tētahi IP mai i te /24 hei utu mō te poraka /30 katoa.

Ko tētahi atu otinga mō te raruraru kore wāhitau ko te hoko me te hoko atu i aua wāhitau i te hokohoko. Hei tauira, i te tau 2017, i ngā miihini o MIT E 14 miriona ngā wāhitau IP kāore anō kia whakamahia e te whare wānanga—ko te nuinga o aua wāhitau i whakatau kia hokona. I puta tētahi kōrero rite i te tīmatanga o Hakihea i Rūhia. I panuitia e te Research Institute for the Development of Public Networks (RosNIIROS) te katinga o tana kairēhita ipurangi ā-rohe, LIR. Whai muri i tēnei, i E tata ana ki te 490 ngā wāhitau IPv4 nō te kamupene Czech, a Reliable Communications. E ai ki ngā tohunga, ko te uara katoa o te puna he $9–12 miriona.
Engari ki te tīmata ngā kamupene ki te hoko anō i ngā IP ki a rātou anō, ki te tipu o ngā ripanga ara. Heoi anō, he otinga anō kei konei - (Kawa Wehewehenga Rapu/Tauira). I konei, e whakaaro ana ngā kaituhi kia whakamahia ngā wāhitau e rua mō te wāhitau whatunga: tētahi mō te tautuhi taputapu, me tētahi mō te waihanga kauhanga i waenga i ngā tūmau. Mā tēnei huarahi ka taea te tango i ngā wāhitau mai i ngā ripanga BGP kāore e taea te whakakotahi ki roto i te poraka kotahi, ka hua ake he puhoi ake te tipu o te ripanga ara. Kei roto hoki i ā rātou otinga te tautoko LISP. ngā kamupene pēnei i a Cisco me LANCOM Systems (e whakawhanake ana i te SD-WAN).
Ko te otinga matua ki te raruraru IPv4 ko te papatipu Ahakoa te whanaketanga o te kawa i ngā tau 20 kua pahure ake nei, kāore anō kia whānuitia te whakamahinga. I tēnei wā, e tautokona ana e te 15% o ngā paetukutuku. Heoi anō, he maha ngā kamupene kei te mahi i ngā mahi hei whakarerekē i te āhuatanga. Hei tauira, he maha ngā kaiwhakarato kapua o te Hauāuru mō ngā IPv4 kāore i whakamahia. Heoi, ka tukuna noa ngā wāhitau kua whakamahia (e hono ana ki te mīhini mariko).
I te nuinga o te wā, kei te harikoa ngā kaihanga taputapu whatunga me ngā kaiwhakarato ratonga ipurangi mō te whakawhiti ki te IPv6. Heoi anō, he maha tonu ngā wero mō te hekenga. Ka whakarite mātou i tētahi tuhinga motuhake mō ēnei wero me ngā otinga.
