Inkcazo yedilesi ye IP loopback / localhost
Idilesi ye-IP 127.0.0.1 yi-IPv4 iinjongo ezikhethekileyo ezibizwa ngokuba yi- localhost okanye idiopback idilesi . Zonke iikhomputha zisebenzise le dilesi njengezo zazo kodwa azivumeli ukuba ziqhagamshelane namanye amacebo afana nedilesi ye-IP yangempela.
Ikhompyutheni yakho inokuba nayo i-192.168.1.115 idilesi ye-IP yangasese eyabelwe kuyo ukuze ikwazi ukunxibelelana ne- router kunye nezinye izixhobo ezinxibelelwano. Nangona kunjalo, kusenalo idilesi ekhethekileyo ye-127.0.0.1 idibene kuyo ukuba ithetha "le khompyutheni," okanye lowo ukhona ngoku.
Idilesi ye-loopback isetyenziswe kuphela yikhompyutheni okhoyo, kunye neemeko ezikhethekileyo kuphela. Oku akufani nedilesi ye-IP evambileyo esetyenziselwa ukudlulisela iifayile kuye nakwezinye iisetyenzisi.
Umzekelo, umncedisi wewebhu osebenza kwikhomputha angakhokelela kwi-127.0.0.1 ukwenzela ukuba amaphepha asebenze ngaphakathi kwaye avivinywe ngaphambi kokuba asetyenziswe.
127.0.0.1 Imisebenzi
Yonke imilayezo eyenziwe yi-software ye- TCP / IP iqulethe iiliti ze-IP kubamkeli bazo; I-TCP / IP ibona i-127.0.0.1 njenge-IP ekhethekileyo idilesi. Umgaqo- nkqubo uhlola umyalezo ngamnye ngaphambi kokuwuthumela kwinethiwekhi yomzimba kwaye ujikeleze ngokuzenzekelayo nayiphi na imilayezo ene-127.0.0.1 ukuya kwisiphelo sokwamkela isitaki se-TCP / IP.
Ukuphucula ukhuseleko lomnatha, i-TCP / IP iphinda ihlole imiyalezo engenayo ifumaneka kwii-routers okanye ezinye iindlela zokunxibelelanisa kwaye ilahle nayiphi na into equle idilesi ye IP. Oku kuvimbela umhlaseli womnatha ukungafihla i-intanethi yenethiwekhi engalunganga njengoko ivela kwidilesi yeloopback.
Iprojekti yesicelo isebenzisa le nxalenye yeloopback kwiinjongo zovavanyo lwendawo. Imiyalezo ethunyelwe kwii-adop i-IP idilesi njenge-127.0.0.1 ayifinyelele ngaphandle kwintanethi yendawo yendawo (LAN) kodwa endaweni yoko ihanjiswa ngqo kwi-TCP / IP kwaye ifumana imigca njengokuba ifikile kumthombo ongaphandle.
Imilayezo yeLoopback iqulethe inombolo yefowuni yokuya kwendawo kwidilesi. Izicelo zingasebenzisa la manani eefowuni ukuhlula imiyalezo yovavanyo kwiindidi ezininzi.
I-Localhost ne-IPv6 Idilesi zeLoopback
Igama lendawo yokuhlala nalo lithetha intsingiselo ekhethekileyo kwiinkqubo zeekhompyutheni ezisetyenziswayo ngokubambisana ne-127.0.0.1. Iifayile zokusebenza zekhompyutha zigcina ukungena kwiifayile zabo zomninimzi ezidibanisa igama kunye nedilesi yeloopback, eyenza izicelo zidale imiyalezo ye-loopback ngegama kunokuba inombhalo ongenqatshelwe.
I-Intanethi ye-Intanethi v6 (IPv6) isebenzisa ingcamango efanayo yedilesi ye-loopback njenge-IPv4. Esikhundleni se-127.0.0.01, i-IPv6 ibonisa idilesi yeloopback nje nje :: 1 (0000: 0000: 0000: 0000: 0000: 0000: 0000: 0001) kwaye, ngokungafani ne-IPv4, ayinikeli uluhlu lweedilesi kule njongo.
127.0.0.1 kunye nezinye iIkheli zePI ezizodwa
I-IPv4 igcina zonke iidilesi kwi-127.0.0.0 ukuya kwi-127.255.255.255 ukuze isetyenziswe kwi-loopback test, nangona i-127.0.0.1 (yintlanganiso yesiganeko) idilesi yeloopback esetyenziswe phantse kuwo onke amacala.
127.0.0.1 kunye nezinye iirejista zenethiwekhi eziyi-127.0.0.0 aziyiyo nayiphi na idilesi ye-IP yangasese ichazwe kwi-IPv4. Idilesi zomntu ngamnye kwiindawo ezizimeleyo zingazinikezelwa kwiidivaysi zenethiwekhi zendawo kunye nokusetyenziswa kwintetho yonxibelelwano lwangaphakathi, kanti i-127.0.0.1 ayikwazi.
Abo bafunda i-computer kwinethiwekhi ngezinye izikhathi badibanisa 127.0.0.1 ngedilesi 0.0.0.0 . Nangona zombini iinguqu ezikhethekileyo kwi-IPv4, i-0.0.0.0 ayinikezeli naluphi na umsebenzi osebenzayo.
