ʻO ka ho'ākākaʻana no ka pilikino IP pilikino / localhost
ʻO ka IP IP 127.0.0.1 kahi helu IPv4 kūikawā kūikawā i kapaʻia kahi localhost a me ka helu loopback . Ke hoʻohana nei nā papahana a pau i kēia helu ma muli o kā lākou pono'ī akāʻaʻole lākou eʻae e kamaʻilio me nā mea'ē aʻe e like me kahiʻano IP.
Loaʻa i kāu kamepiula i ka 192.168.1.115 kelepona IP pono'ī i hāʻawiʻia iā ia i hiki ai iā ia ke kamaʻilio me kahi alalai a me nā mea'ēhana'ē aʻe. Eia nō naʻe, aia kēia 127.0.0.1 kūlana i pili iā ia me ka manaʻo o "kēia kamepiula," a iʻole paha i kēia manawa.
ʻO ka pilina pilikino e hoʻohana waleʻia ana e ke kamepiula āu e noho nei, a no nā kūlana kūikawā wale nō. ʻAʻole like kēia me kahi IP IP i hoʻohana mauʻia e hoʻololi i nā pūnaewele a i nā mea'ē aʻe'ē aʻe.
Eia kekahi laʻana, hiki i kahi pūnaewele pūnaewele e holo ana ma luna o kahi kamepiula ke kuhikuhi i 127.0.0.1 i hiki ai ke holo i nāʻaoʻao ma ka'āina a ho'āʻoʻia ma mua o ka hoʻolālāʻana.
Pehea 127.0.0.1 Hana
ʻO nā leka a pau i hanaʻia e nā polokalamu polokalamu TCP / IP he mau helu IP no nā mea i loaʻa iā lākou; Hoʻomaopopoʻo TCP / IP i ka 127.0.0.1 ma kahi helu IP kūikawā. Hoʻopili ke kuʻina i kēlā me kēia memo ma mua o ka hoʻounaʻana iā ia i kahi pūnaewele a lawe pū me ka leka uila i nā leka me ka destination o 127.0.0.1 hoʻi i ka hopena loaʻa o ka waihona TCP / IP.
No ka hoʻonuiʻana i ka paleʻana i ka pūnaewele, e nānā pū anaʻo TCP / IP i nā memo e hiki mai ana ma luna o nā mīkini a me nā'īpuka pūnaewele a hoʻokaʻawale i nā mea i loko o nā papa inoa IP. Ke pale nei kēia i ka mea hoʻopuka pūnaewele mai ka hoʻololiʻana i kā lākou mau pūnaewele pūnaewele maikaʻi ma mua o ka heleʻana mai kahi wāwae loopback.
Ke hoʻohana nei nā polokalamu hoʻolālā i kēiaʻano loopback no nā hoʻonalohua kaiaulu. Nā leka i hoʻounaʻia i nā inoa IP loopback e like me 127.0.0.1 iʻole e puka i waho i ka pūnaewele wahi o ka LAN (LAN) akā e hāʻawi pololeiʻia i ka TCP / IP a loaʻa nā luina me he mea lā i hōʻea mai lākou mai kahi kumu waho.
Aia nā loopback o ka helu i kahi helu kikowaena me ka hoʻohui. Hiki i nā noi ke hoʻohana i kēia mau helu kelepona e hoʻokaʻawale i nā leka uila i nāʻano he nui.
Localhost a me IPv6 Loopback Addresses
He inoa kūikawā hoʻi ka inoa o ka hale inoa ma ka pūnaewele pūnaewele i hoʻohanaʻia me 127.0.0.1. Hoʻomau ka papa hana hoʻolālā i ke komoʻana i nā pūnaewele o kā lākou pūnaewele e kākoʻo ana i kahi inoa me ka helu loopback, e hiki ai i nā noi ke hana i nā memo loopback ma o ka inoa ma mua o ka helu paʻakikī.
ʻO ka v6 (IPv6) hōʻano pūnaewele ke hoʻohana nei i ka manaʻo like o kahi address loopbackʻo IPv4. Ma kahi o 127.0.0.01,ʻo IPv6 kahi i heluʻia ai kona wahi helu ma ka'ena'ī: 1 (0000: 0000: 0000: 0000: 0000: 0000: 0000: 0001) a, likeʻoleʻo IPv4,ʻaʻole e hoʻokaʻawale i nāʻano kūkeke no kēia kumuhana.
127.0.0.1 a me kekahi mau'ōlelo kūikawā kūikawā
Hiki i ka IPv4 mālama i nā kuhi a pau ma 127.0.0.0 a hiki i 127.255.255.255 no ka hoʻohanaʻana i nā hoʻokolohua loopback,ʻoiai 127.0.0.1 ke (ma ka hālāwai kūikawā) i ka helu loopback i hoʻohanaʻia i nā mea a pau loa.
ʻO 127.0.0.1 a me nā lālā 127.0.0.0'ē aʻeʻaʻole i kekahi o nā papa helu IP kūikawā i hōʻikeʻia i ka IPv4. Hiki ke hoʻolaʻaʻia nā kuhi o kēlā me kēia kanaka ma nā pūnaewele pūnaewele i nā pūnaewele pūnaewele āpau e hoʻohana ai no ka loiloi waena, akāʻo 127.0.0.1 hikiʻole.
ʻO ka poʻe i aʻo i ka lolouila pūnaewele i kekahi manawa e hoʻopilihoi lākou i ka 127.0.0.1 me kahi helu 0.0.0.0 . ʻOiai heʻelua mau manaʻo kūikawā ma IPv4, 0.0.0.0ʻaʻole i hāʻawi i kekahi hana loopback.
