Usavhunduka: ese IPv4 adhiresi atopera

Y hapasisina IPv4 kero hapachina. Zvakaitika nezuro, Kukadzi 3, apo mabhuroko mashanu ekupedzisira ayo IANA akagovera pakati penzvimbo shanu dzenyika dzakapihwa. Kugoverwa kwave kwakaenzana pakati peARIN (North America), LACNIC (Latin America uye zvimwe zvitsuwa zveCaribbean), RIPE NIC (Europe, Middle East neCentral Asia), AfriNIC (kondinendi yeAfrica) neAPNIC (East Asia nenharaunda yeRunyararo. ). Zvinotarisirwa kuti IPv4 kero dzakatopihwa kare, mumaoko emasangano akasiyanasiyana enharaunda anovatungamira, yekupedzisira kusvika gunyana. Asi kubva panguva iyoyo hapazovi nezvimwe. Chero ani zvake anoda nyowani yeInternet chinongedzo achagamuchira imwe yeiyo mhando IPv6.

Iyo IP kero nzvimbo yakapihwa ne IPv4 i32 bit (4.294.967.296 IP kero). IPv6 ndeye 128-bit kero nzvimbo, iyo inoshandurwa kuve nhamba yemakero, inhamba yekudenga (340 sextillion IP kero). Pakarongwa IPv4, 4.300 bhiriyoni IP kero dzakaita sedzakakwana muma70, asi svondo rino vapera.

Pane zvikonzero zvinoverengeka zvekuti izvi zviitike. Nechinhu chimwe chete, chete 14% ye IP kero anoshandiswa zvinobudirira Basa harina kuitwa zvakaringana munguva yakapfuura, kunyanya muma80, mumakore iwayo Internet haina kuwedzerwa kupfuura masainzi, yunivhesiti nehurumende minda.

Dambudziko rakakosha nderekuti IPv4 ne IPv6 hazviwirirane. IPv4 adhiresi anoumbwa nemapoka mana emanhamba ane kukosha kwazvo makumi maviri neshanu (semuenzaniso: 4) uye iwo anowirirana neIpv255 ane mapoka masere eane hexadecimal manhamba anogona kumanikidzwa kana chero boka riri "null".

Iko kuedza kweshanduko kuchadonha kune vanopa Internet sevhisi, vanoshandisa network, uye makuru masuo. Mushandisi wemba haafanire kuona chero chinhu, kunyangwe mune yepakati term isu tingangoda kuchinja router. Neraki, masisitimu emazuva ano anoshanda, uye kunyanya iwo anoshongedza nharembozha, inotsigira IPv6.
