Umbuzo: Kuyini IPv4? I-IPv6? Kungani Lokhu Kubalulekile?
Mhlawumbe ufunde ukuthi i-IPv4 'iphuma ngamakheli', nokuthi i-'Pv6 'entsha izoxazulula inkinga. Nakhu.
Impendulo: Kuze kube lehlobo, izwe lasemngciphekweni wokuphuma kwamakheli ekhompuyutha atholakalayo . Uyabona, yonke idivayisi exhuma kwi-intanethi idinga inombolo ye-serial , kufana nayo yonke imoto esemthethweni emgwaqeni idinga ipuleti yelayisense.
Kodwa njengezinhlamvu ezingu-6 noma ezingu-8 zephayisensi yelayisensi zinqunyelwe, kunomkhawulo wemathemitha ukuthi zingaki amakheli ahlukene angakhona kumadivayisi e-Intanethi.
Uhlelo lokuqala lokuxhumanisa i-intanethi lubizwa ngokuthi 'Inthanethi Protocol, Version 4' ( IPv4 ), futhi libalile amakhompyutha we-Intanethi ngempumelelo iminyaka . Ngokusebenzisa ama-32-bits wezinombolo eziphindwe kabusha, I-IPv4 inamakheli angama-4.3 ayizigidi.

Isibonelo sekheli le-IPf4: 16.202.228.105
Bona izibonelo eziningi zekheli le-IPv4 lapha .
Manje, ngenkathi amakheli ayizigidi ezingu-4,3 angase abonakale eningi, i-intanethi izodlulela le nombolo yamadivayisi ngasekupheleni kuka-2012. Njalo ikhompyutha, yonke i-cell phone, zonke i-iPad, yonke iphrinta, yonke i-Playstation, ngisho nemishini ye-soda idinga ikheli le-IP . Awekho amakheli we-IPv4 okwanele kuwo wonke lawa madivayisi!
Izindaba ezinhle: uhlelo olusha lokubhekana ne-intanethi lulapha, futhi luzogcwalisa isidingo sethu samakheli amaningi wekhompyutha .
I-Protocol Protocol version 6 (i- IPv6 ) okwamanje isusiwe emhlabeni wonke, futhi uhlelo lwayo lokukhulisa i-IPR4 luzokwenza ukulungiswa kwe- IPv4 . Uyabona, i-IPv6 isebenzisa ama-128 bits esikhundleni sama-bits angu-32 ngamakheli ayo, okudala ama-3.4 x 10 ^ 38 amakheli akhona (okungukuthi 'ama-trillion-trillion-trillion'; i-undecillion 'yisikhathi esingavamile esichaza le namba enkulu engenakwenzeka).
Lezi zigidigidi zama-IPv6 amakheli amasha zizohlangabezana nesidingo se-intanethi sekusasa elibikezelayo.

Isibonelo sekheli le-IPv6 : 21DA: D3: 0: 2F3B: 2AA: FF: FE28: 9C5A

Iphasi lishintshe nini ngokugcwele ku-IPv6?
Impendulo: umhlaba usuvele uqalile ukwamukela i-IPv6, nezindawo ezinkulu zewebhu ze-Google ne-Facebook ezenza ngokusemthethweni kusukela ngoJuni 2012. Ezinye izinhlangano zihamba kancane kunokuba abanye benze ushintsho. Ngoba ukudlulisa ikheli ngalinye lwedivayisi kungadinga ukuphathwa okuningi, lokhu kushintshwa okukhulu ngeke kuqedele ubusuku bonke. Kodwa ukuphuthuma kukhona, futhi izinhlangano zangasese kanye nohulumeni empeleni ziyashintsha manje. Lindela i-IPv6 ibe yindinganiso yendawo yonke ngasekupheleni kuka-2012.
Ingabe ushintsho lwe-IPv4-to-IPv6 lungithinta?
Impendulo: ushintsho luzobonakala lungabonakali kubasebenzisi abaningi bekhompyutha. Ngenxa yokuthi i-IPv6 izokwenzeka ngokuyinhloko ngemuva kwemifanekiso, ngeke kudingeke ufunde noma yini entsha ukuze ube umsebenzisi wekhompyutha, futhi ngeke wenze noma yini ekhethekile ukuba neyakho idivayisi yekhompyutha. Ngonyaka ka-2012, uma ugcizelela ekunikezeni idivayisi endala nge-software edala, ungase udinge ukulanda ama-patches akhethiwe e-software ukuze uhambisane ne-IPv6.
Kungenzeka ukuthi uzothenga ikhompyutha entsha noma i- smartphone entsha ngo-2012, futhi izinga le-IPv6 lizobe selifakwe ngaphakathi kuwe.
Ngamafuphi, ushintsho oluvela ku- IPv4 kuya ku-IPv6 aluhle kakhulu noma luyesabeka kunokuba ushintsho lwe-Y2K lube. Kuyinkinga enhle ye-techno-trivia ukuze uqaphele, kodwa ayikho ingozi yokulahlekelwa ukufinyelela kwi-Inthanethi ngenxa yenkinga yokubhekana ne-IP. Ukuphila kwekhompyutheni yakho akumele kuphazamiseke kakhulu ngenxa yenguqu ye-IPv4-to-IPv6. Vele usetshenziselwe ukusho 'IPv6' ngokuzwakalayo njengendaba yokuphila kwikhompyutha evamile. +
