Umbuzo: Yintoni IPv4? IPv6? Kutheni Oku Kubalulekile?
Mhlawumbi uye wafunda ukuba i-IPv4 'iphuma ngeedesi', kwaye i-'Pv6 'entsha iya kusombulula ingxaki. Nasi isizathu.
Impendulo: Kuze kube ngeli lihlobo, ihlabathi lasemngciphekweni wokuphuma kwiikhowudi zekhompyutha . Uyabona, zonke iifowuni ezidibanisa kwi-intanethi zidinga inombolo ye - serial , njengokuba yonke imoto esemthethweni endleleni ifuna ipenethi yelayisenisi.
Kodwa njengamahlamvu angama-6 okanye a-8 wepenethi yelayisenisi ayilinganiselwe, kukho umda wemathematika ukuya kwiidilesi ezahlukeneyo ezinokwenzeka kwii-intanethi.
Inkqubo yokuqala ye-intanethi ye-intanethi ibizwa ngokuthi 'iProtokholi ye-intanethi, i-Version 4' ( IPv4 ), kwaye ibale iikhomputha ze-Intanethi ngempumelelo iminyaka . Ngokusebenzisa ama-32 bits of numbers recombined, i-IPv4 ine-adresi ye-4.3 yezigidi ezikhoyo.
Umzekelo Idilesi ye-IPf4: 68.149.3.230
Isibonelo se IPf4: 16.202.228.105
Bona imizekelo engaphezulu yee-IPv4 iilesi apha .
Ngoku, ngelixa iidilesi eziyi-4.3 zeebhilidi zingabonakala zininzi, i-intanethi yayiza kudlulela le nombolo yezixhobo ngasekupheleni konyaka we-2012. Nganye ikhompyutheni, yonke ifowuni, iifowuni nganye, yonke iprinta, yonke i-Playstation, kunye nemishini ye-soda idinga idilesi ye-IP . Ayikho idilesi ye IPv4 ngokwaneleyo kuzo zonke ezi zixhobo!
Iindaba ezilungileyo: i-intanethi entsha ye-intanethi ilapha, kwaye iya kuzalisa imfuno yethu yee-adware ezininzi .
IProtokholi ye- Intanethi ye-6 ( IPv6 ) ngoku iqhutywe kwihlabathi lonke, kwaye inkqubo yayo yokukhulisa i-adware iya kulungisa umda we- IPv4 . Uyabona, i-IPv6 isebenzisa ii-128 bits esikhundleni se-32 bits kwiithalesi zayo, ukudala i-3.4 x 10 ^ 38 iidilesi ezinokwenzeka (i-trillion-trillion-trillion); i-undecillion "lixesha elifihlakeleyo elichaza le nombolo enkulu engenakwenzeka).
Ezi zigidigidi zee-IPv6 dilesi ziza kuhlangabezana neemfuno ze-intanethi yekamva elibonakalayo.
Isibonelo se IPv6: 3ffe: 1900: 4545: 3: 200: f8ff: fe21: 67cf
Isibonelo se IPv6 : 21DA: D3: 0: 2F3B: 2AA: FF: FE28: 9C5A
Bona imizekelo engakumbi ye IPV6 dilesi apha.
Liliphi ixesha ihlabathi eliguqula ngokupheleleyo kwi IPv6?
Impendulo: ihlabathi sele liqalise ukuvumelanisa IPv6, kunye neendawo ezinkulu zewebhu zeGoogle kunye ne-Facebook ezenza ngokusemthethweni ngoJuni 2012. Enye imibutho ihamba kancane kunokuba abanye benze ishintsho. Ngenxa yokwandisa idilesi nganye yesicatshulwa ifuna i-administration eninzi, ukutshintshela okukhulu akuyi kuzaliswa ngobusuku bonke. Kodwa ukuphuthuma kukhona, kwaye imibutho yabucala kunye noorhulumente ngokwenene ishintsho ngoku. Lindela i-IPv6 ibe ngumgangatho wendawo yonke ngasekupheleni kuka-2012.
Ngaba i-IPv4-to-IPv6 iyitshintshe?
Impendulo: utshintsho luya kubonakala lungabonakali kubasebenzisi abaninzi bekhompyutha. Ngenxa yokuba i-IPv6 iya kwenzeka ngokubanzi emva kweemifanekiso, awuyi kufundwa nantoni na entsha ukuba ngumsebenzisi wekhompyutheni, kwaye akuyi kuyenza nantoni na ekhethekileyo ukuba ube nefowuni yekhompyutha. Ngo-2012, ukuba ugxininisa ukuba unesidala esisekudala ngesoftware, ungadinga ukukhuphela ii-patches ezikhethekileyo ze-software ukuze zihambelane ne-IPv6.
Okunokwenzeka ukuba uya kuthenga ikhompyutha entsha okanye i- smartphone entsha ngo-2012, kwaye umgangatho we-IPv6 uza kufakelwa kwangaphambili kuwe.
Ngamafutshane, umtshini ovela kwi- IPv4 ukuya ku-IPv6 awunanto ephawulekayo okanye eyoyikisayo kunokuba utshintsho lweY2K lwalukho. Ingxaki efanelekileyo ye-techno-trivia ukuba iyazi, kodwa akukho mngcipheko wokulahlekelwa ukufikelela kwi-intanethi ngenxa ye-IP yokukhankanya ingxaki. Ubomi bakho bekhompyutheni bungafanelekanga kakhulu ngenxa yenguqu ye-IPv4-to-IPv6. Yenza nje ukuthetha ngokuthi 'IPv6' ngokuvakalayo njengento yokuphila kwikhompyutha rhoqo. +
