Tsanangudzo ye loopback IP address / localhost
I IP address 127.0.0.1 inzvimbo inokosha yePv4 address inonzi " homehost" kana " loopback address" . Makombiyuta ose anoshandisa kero iyi seyake asi haaitenderi kuti vataure nemamwe mafaira akaita se IP address chaiyo inoita.
Kombiyuta yako inogona kunge iine 192.168.1.115 kero yepaI yega yega yega iyo yakagoverwa kuitira kuti iyanane ne router nedzimwe mawambo akabatana. Kunyange zvakadaro, ichi chichiri chinhu ichi chinokosha 127.0.0.1 kero yakanamatirwa kureva kureva "iyi kombiyuta," kana iyo yamunenge uripo.
Iroodback address inoshandiswa chete nekombiyuta uripo, uye chete pamamiriro ezvinhu chaiwo. Izvi hazvina kufanana neIndaneti yenguva dzose iyo inoshandiswa kuendesa mafaira kune uye kune mamwe maedhi akabatanidzwa.
Semuenzaniso, web server inoshandisa pakombiyuta inogona kureva 127.0.0.1 kuitira kuti mapeji anokwanisa kushandiswa munzvimbo uye akaedzwa vasati vashandiswa.
Nhamba 127.0.0.1 Inoshanda
Yese mharidzo inogadzirwa neTCP / IP software yekushandisa ine IP mazita evakagamuchirwa; TCP / IP inoona 127.0.0.1 senhare ye IP. Iyo protocol inotarisa mharidzo imwe neimwe isati yaendesa iyo yepanyama uye inongodzokazve nzira chero ipi zvayo mharidzo ine nzvimbo yekuenda 127.0.0.1 kumashure kumugumo wokugamuchira weTCP / IP paki.
Kuvandudza mitambo yekuchengeteka, TCP / IP inotarisawo mhinduro dzinouya dzinosvika pairi routa kana dzimwe nhepfenyuro dzemagetsi uye dzinodzinga chero chipi zvacho chine loopback IP kero. Izvi zvinodzivisa mutengesi wenhare kubva kuvanza mavhiringidzi ematokari emigwagwa sezvavanouya kubva kudilesi ye loopback.
Kushandisa software zvinowanzoshandisa chinhu ichi chinoshandiswa pamigwagwa yekuedza. Mharidzo yakatumirwa ku loopback IP keroti se 127.0.0.1 haifaniri kusvika kune imwe nzvimbo yenzvimbo (network) yenzvimbo (LAN) asi panzvimbo payo inowanikwa zvakananga kuTCP / IP uye inogamuchira mitsetse sokunge yakave yakabva kune imwe kunze.
Mharidzo yeLoopback ine nhamba yekufambisa inosvika kune imwe kero. Zvirongwa zvinogona kushandisa idzi nhamba dzenhamba kuti zviparadzanise mhinduro dzekuongorora mumapoka akawanda.
Localhost uye IPv6 Address Loopback
Zita rokuti localhost rinotakurawo zvakananga mumashandisi emakombiyuta anoshandiswa pamwe chete ne 127.0.0.1. Makombiyuta ekushanda maitiro anochengetedza kupinda mukati mafaira evatori vekubatanidza zita nezita reloopback, zvichiita kuti mapurogiramu aumbe mharidzo yeLoopback kuburikidza nezita panzvimbo pane nhamba isina kukwana.
Internet Protocol v6 (IPv6) inoshandisa pfungwa imwechete yekodzero ye loopback se IPv4. Panzvimbo pe 127.0.0.01, IPv6 inomiririra dhesi yeloopback sezvinoti: 1 (0000: 0000: 0000: 0000: 0000: 0000: 0000: 0001) uye, kusiyana nePv4, haina kupa mazita eatari nokuda kwechinangwa ichi.
127.0.0.1 vs. Zvimwe Mazano Akakosha eP IP
IPv4 inochengetedza mazita ose mu 127.0.0.0 kusvika 127.255.255.255 kuti ishandiswe mu loopback kuedza, kunyange zvazvo 127.0.0.1 iine (neyakaitika gungano) nhau ye loopback inoshandiswa munenge mamiriro ese ezvinhu.
127.0.0.1 uye imwe 127.0.0.0 matarenda emitauro haisi yevamwe vepachena pikero yepaIndaneti inotsanangurwa mu IPv4. Mamwe mazita ari munharaunda yega yega inogona kutsaurirwa kumagetsi ekushandisa maitiro uye kushandiswa kwekutaurirana kwe-inter-device, asi 127.0.0.1 haigone.
Avo vanodzidzira kombiyuta yekutengesa dzimwe nguva vanovhiringidza 127.0.0.1 nekero 0.0.0.0 . Kunyange zvazvo zvose zviri zviviri zvinoreva zvakananga kuPv4, 0.0.0.0 hazvipi zvese zvinogadzirisa zvinoshanda.
