URLs thiab IP qhov chaw yog ob tog ntawm tib lub nyiaj npib
Hauv kev sib tham, IP chaw saib xyuas yog hais txog tus txheej txheem ntawm kev txhais lus nruab nrab ntawm tus IP chaw nyob thiab cov npe hauv internet. Forward IP chaw nrhiav ua ib lub npe hauv internet rau IP chaw nyob. Rov qab IP chaw nrhiav yuav hloov IP naj npawb rau lub npe. Rau feem coob ntawm cov neeg siv computer, txoj kev ua no tshwm sim tom qab lub scenes.
Tus IP Qhov Chaw Yog Dab Tsi?
Qhov Internet Protocol Address (IP Chaw Nyob) yog ib cim tshwj xeeb uas tau muab xam rau cov khoom siv xws li computers, smartphones thiab tablets. Ib qho chaw tus IP yog siv los cim tus cim tshwj xeeb thiab chaw nyob. IPv4 chaw nyob yog 32-npawb xov tooj, uas muaj peev xwm muab tau li ntawm 4 billion tus lej. Tshaj tshiab ntawm IP raws tu qauv (IPv6) muaj ib qho tsawg kawg nkaus ntawm cov chaw nyob.
Piv txwv li, ib qho IPv4 chaw zoo li 151.101.65.121, thaum IPv6 chaw nyob zoo li 2001: 4860: 4860 :: 8844.
Vim li cas IP Address Lookup Exist
IP chaw nyob yog ib txoj hlua ntev uas nyuaj rau cov neeg siv computer siv los nco, thiab nws yog ib qhov raug tau teeb meem tsis zoo. Xwb, cov neeg siv computer nkag cov URLs mus rau cov websites. Cov URLs yoojyim nco qab thiab tsis tshua muaj kev txwv tsis raug. Txawm li cas los xij, URLs yuav tsum muab xa mus rau cov lus qhia IP uas muaj qhov ntev, ces lub computer paub qhov twg mus.
Cov neeg siv hom ntaus ntawv hauv qhov web browser ntawm lawv lub computer los yog mobile device. Lub URL mus rau lub router lossis modem, uas ua tau rau cov Kev Xa Mus Rau Chaw Xa Ntawv (DNS) saib siv lub rooj sib tham. Lub chaw tus IP tshwm sim qhia qhov website uas tus neeg siv xav saib.

Feem coob cov neeg tsis tshua xav tau kev txhawj xeeb nrog cov IP zoo dua. Lawv siv feem ntau rau cov teeb meem network, feem ntau yuav nrhiav tau tawm lub npe ntawm tus IP chaw nyob uas ua rau muaj teeb meem.
Kev Nrhiav Kev Pab
Muaj ntau cov kev pabcuam hauv kev pabcuam hauv internet los txhawb thiab nrhiav IP rov rau cov chaw nyob . Hauv internet, cov kev pab cuam no vam khom lub Domain Name System thiab raug hu ua DNS lookup thiab rov qab saib DNS cov kev pabcuam.
Hauv ib lub tsev kawm ntawv los yog cov koom ua haujlwm hauv zos , qhov chaw seem IP chaw nyob yog qhov ua tau. Cov tes hauj lwm no siv cov npe hauv tsev ua haujlwm uas ua haujlwm zoo sib xws rau cov neeg ntawm DNS cov chaw hauv internet. Ntxiv rau DNS, lub Windows Internet Naming Service yog lwm yam tshuab uas siv los txhim kho cov kev pab cuam ntawm IP ntawm cov chaw hauj lwm.
Lwm txoj kev Naming
Xyoo dhau los, ua ntej lub advent ntawm dynamic IP addressing, ntau lub lag luam me me ua lag luam tsis muaj npe lub npe thiab tswj tus kheej IP lookups los ntawm cov ntaub ntawv hauv cov ntaub ntawv. Hosts cov ntaub ntawv muaj cov npe yooj yooj yim ntawm IP chaw nyob thiab lub computer cov npe. Qhov kev tshawb nrhiav IP no tseem siv rau qee qhov Unix computer network. Nws kuj siv tau rau hauv cov tes hauj lwm hauv tsev uas tsis muaj tus router thiab nrog qhov chaw nyob IP nyob hauv chaw.
Dynamic Host Configuration Protocol (DHCP) yeej tswj cov chaw tus IP nyob hauv lub network. DHCP -tsis siv network yuav cia siab rau DHCP tus neeg saib xyuas kom muaj cov ntaub ntawv sau tseg. Hauv ntau lub tsev thiab cov lag luam me, tus router yog DHCP tus neeg siv. Ib tug neeg DHCP tus neeg tau txais kev pabcuam pom muaj ntau ntawm IP chaw, tsis yog ib tus IP chaw nyob. Yog li ntawd, IP chaw nyob yuav txawv qhov ntxiv tom qab ib tug neeg nkag mus rau qhov URL. Siv ib qhov chaw ntawm IP chaw tso cai rau ntau tus neeg mus saib lub website ib txhij.
Cov kev pabcuam txuas mus rau hauv lub koos pij tawj nrog lub koos piv tawj hauv lub computer khiav hauj lwm pub IP chaw nyob ntawm ob leeg ntiag tug LANs thiab hauv internet. Nyob rau hauv Windows, piv txwv li, tus nslookup hais kom ua kev txhawb zog ntawm cov npe ntawm cov npe servers thiab hom ntaub ntawv. Tseem muaj pej xeem nslookup qhov chaw hauv internet xws li Name.space, Kloth.net, Network-Tools.com, thiab CentralOps.net.
