Ama-URL namakheli we-IP yizinhlangothi ezimbili zemali efanayo
Ekuxhumaneni, ikheli le-IP lookup lisho inqubo yokuhumusha phakathi kwamakheli e-IP namagama wesizinda we-intanethi. Ngaphambili ikheli le-IP lookup liguqula igama le-inthanethi kwikheli le-IP. I-reverse ikheli le-IP lookup liguqula inombolo ye-IP egameni. Kubaningi babasebenzisi bekhompyutha, le nqubo ivela ngemuva kwezigcawu.
Iyini ikheli le-IP?
Ikheli le-Intanethi ye-Intanethi (Ikheli le-IP) yinombolo eyingqayizivele eyabelwe amadivaysi e-computing afana namakhompyutha, ama-smartphones namaphilisi. Ikheli le-IP lisetshenziselwa ukukhomba idivaysi ehlukile nekheli. Amakheli we-IPv4 ayizinombolo ezingu-32-bit, ezinganikeza ngezinombolo eziyizigidi ezingu-4. Inguqulo entsha yenqubo ye-IP (IPv6) inikeza inombolo engapheliyo yamakheli ayingqayizivele.
Isibonelo, ikheli le-IPv4 libukeka njengo-151.101.65.121, kanti ikheli le-IPv6 libukeka njengo-2001: 4860: 4860 :: 8844.
Kungani ikheli le-IP lookup likhona
Ikheli le-IP yinkomba ende yezinamba ezinzima kunoma yimuphi umsebenzisi wekhompiyutha ukukhumbula, futhi iyakwazi ukuthola amaphutha we-typographical. Esikhundleni salokho, abasebenzisi bekhompuyutha bangena ama- URL ukuya kumawebhusayithi. Ama-URL kulula ukuwakhumbula futhi angenakukwazi ukuqukatha amaphutha we-typographical. Noma kunjalo, ama-URL kufanele ahunyushwe kumakheli we-IP ambalwa ambalwa, ngakho ikhompyutha iyazi ukuthi uzoya kuphi.
Abasebenzisi abajwayelekile bahlela i-URL kwisiphequluli sewebhu kukhompyutha yabo noma kudivayisi yeselula. I-URL iya kwi-router noma i-modem, eyenza i-Domain Name Server phambili (DNS) yokuvula ngokusebenzisa ithebula lokuhambisa. Ikheli le-IP eliholele likhomba iwebhusayithi oyifunayo ofuna ukuyibona. Le nqubo ayibonakali kubasebenzisi ababona kuphela iwebhusayithi ehambelana ne-URL ayibhala kwibha yekheli.
Abasebenzisi abaningi abadingeki ukuthi bakhathazeke nge-lookups ye-IP ephindaphindiwe. Zisetshenziselwa kakhulu ukuxazululwa kwenethiwekhi, ngokuvamile ukuthola igama lesizinda lekheli le-IP elibangela inkinga.
Izinsizakalo Zokungena
Izinsizakalo eziningana ze-intanethi zisekela kokubili phambili futhi ziguqule kabusha i-IP yokuthola amakheli omphakathi . E-intanethi, lezi zinsizakalo zithembele ku- Domain Name System futhi ziyaziwa ngokuthi i- DNS lookup futhi ziphinde zinikeze izinsizakalo ze-DNS lookup.
Esikhathini senethiwekhi noma inethiwekhi yendawo yenkampani , ama-lookups e-IP yangasese nawo angenzeka. Lawa amanethiwekhi asebenzisa amaseva wangaphakathi wangaphakathi enza imisebenzi efana nalawo amaseva e-DNS ku-intanethi. Ngaphezu kwe-DNS, i- Windows Internet Naming Service ingenye ubuchwepheshe obungasetshenziselwa ukwakha amasevisi wokuthola i-IP kumanethiwekhi angasese.
Ezinye izindlela zokubiza
Eminyakeni edlule, ngaphambi kokufika kwe-IP enamandla, amanethiwekhi amaningi amabhizinisi amancinci ayinamaseva wegama futhi alawulwa yi-IP lookups yangasese ngokusebenzisa amafayela wesandla. Ama-host amafayela aqukethe uhlu olulula lwamakheli e-static e-IP namagama e-computer ahlobene. Le ndlela yokubheka i-IP isasetshenziselwa amanethiwekhi amakhompyutha e-Unix. Kungasetshenziselwa futhi kumanethiwekhi asekhaya ngaphandle kwe-router futhi nge-IP static ukubeka endaweni.
I-Dynamic Host Configuration Protocol (DHCP) ilawula ngokuzenzakalelayo amakheli e-IP ngaphakathi kwenethiwekhi. Amanethwekhi ase- DHCP ancike kuseva ye-DHCP ukulondoloza amafayela asuselwa kuwo. Emakhaya amaningi namabhizinisi amancane, i-router iyiseva ye-DHCP. Iseva ye-DHCP ihlonipha amakheli we-IP, hhayi ikheli elilodwa le-IP. Ngenxa yalokho, ikheli le-IP lingase lihluke ngesikhathi esizayo umsebenzisi angena ku-URL. Ukusebenzisa amakheli amaningi we-IP kuvumela abantu abaningi ukuba babheke lewebhu ngesikhathi esisodwa.
Izinhlelo zesevisi ezihlinzekwa ngesistimu yokusebenza yenethiwekhi zivumela ikheli le-IP lookups kuma- LAN angasese kanye ne-intanethi. Ku-Windows, isibonelo, umyalo we- nslookup usekela i-lookups ngamaseva wegama futhi uphatha amafayela. Kukhona namasayithi we-nslookup asesidlangalaleni kuhlanganise ne-Name.space, Kloth.net, Network-Tools.com, ne-CentralOps.net.
