He aha kahi kikowaena DNS?
kahi o ka huaʻōlelo (ʻŌnaehana inoa kikowaena) i ʻelua mea, ʻo ka mua ka protocol i hoʻohana ʻia i kēia lā i ka hapanui o nā hihia e hoʻololi i nā lepili heluhelu (E like me nā inoa inoa kamepiula) i nā helu uila, ʻo ka lua ka hana honua o ke kūkulu ʻana i kahi lawelawe e hoʻohana ana i kēia kaola e hiki ai ke kamaʻilio.
a ʻo ka pākuʻina kau he pōkole no kikowaena inoa kikowaena ʻOkakopa ʻōnaehana inoa kikowaena
ʻO ka ʻōnaehana inoa kikowaena (pākuʻina kau) kahi hoʻonohonoho o ka ʻikepili pūnaewele i unuhi i nā hostnames i nā IP address.
Kuhi pinepine ʻia ʻo DNS ma ke ʻano he puke puke o ka Pūnaewele no ka mea hoʻololi ia i nā inoa inoa maʻalahi e hoʻomanaʻo e like me www.google.com i nā IP address e like me 216.58.217.46.
Hana ia ma hope o nā hiʻohiʻona ma hope o ke kikokiko ʻana i ka URL i ka pahu helu o ka polokalamu kele pūnaewele me ka ʻole o ka mea hoʻohana e ʻike nei i kēia kaʻina. makemake mākou e kipa.
Nā Pae Hoʻomaka DNS
Ua hala kēia lawelawe i loko o nā hanauna ʻekolu a hiki i kona ʻano a maʻamau.
● hanauna mua
Ma hope o kekahi mau hoʻāʻo mua e hoʻokipa i nā pūʻali ma o ka Pūnaewele, ua hana kahi hui o nā ʻenekini i kahi wehewehe DNS.
Ua hana ʻia kēia hana ma loko o ka Pūnaehana Hana ʻenehana Pūnaewele (IETF) a me nā palapala i kau ʻia i ka Request for Comment series (RFC), wehewehe kēia palapala i kahi protocol hana piha a hoʻokomo i kekahi o nā ʻano ʻikepili e lawe ʻia.
Ua ʻike ʻia nā leka uila pūnaewele a ua hoʻāʻo ʻia e ʻae i nā leka e hoʻohana nui i pākuʻina kau. ʻOiai ʻo nā hoʻāʻo ʻē aʻe i ukali e hoʻohui i nā hiʻohiʻona kikoʻī i ka DNS, ʻaʻole ia i hoʻopili ʻia no ka mea ma hope ua huli ia ʻaʻole ia ka manaʻo o ka hoʻopili ʻana i nā polokalamu ʻē aʻe i ka DNS. pākuʻina kau Manaʻo maikaʻi a ma kahi paha o 10 mau makahiki ma mua o ka paʻi ʻia ʻana o ka loiloi protocol mua loa pākuʻina kau ʻO ka mea e hoʻohui i kahi ala hōʻeuʻeu e mālama i nā kikowaena i kēia lā ma o ka hoʻohana ʻana i nā ʻano hana i kapa ʻia HOOLAHA a me ka hoʻoili ʻāina hoʻonui (IXFR), i ka hanauna mua o pākuʻina kauʻO ke ala ʻoi loa e hoʻolako i ka hoʻomau ʻana ʻo ia ka loaʻa ʻana o nā kikowaena i nā nīnau he nui. Ua kapa ʻia hoʻokahi kikowaena ka haku pūnaewele (kahu kikowaena), ʻo ke koena he mau kauā kauā (kauā kauā), a ua kauoha ʻia kēlā me kēia kauā kauā e nānā i ka kikowaena kikowaena i kēlā me kēia manawa e hoʻoholo inā ua loli ka ʻikepili a ʻaʻole paha.
● ka hanauna ʻelua
ʻoi aku HOOLAHA ʻO ka mea hoʻololi pāʻani mua, ma kahi o ke kahu kikowaena e kali ai no ka nānā ʻana o nā kauā kauā, hiki iā ia ke hoʻouna i kahi leka hoʻomaopopo i nā kauā kauā, e hoʻonāukiuki iā lākou e kiʻi i ka ʻike hou. I ka manawa like i mālama ʻia ai IXFR hoʻololi nui i ke ʻano o ka launa ʻana o ka ʻikepili;
Ma mua o ka hoʻololi ʻana i hoʻokahi wale nō moʻohelu o nā haneli e hōʻike ana ka hōʻike kumu i nā leka he haneli, ʻoiai e loli nei IXFR ʻAe wale ka ʻōnaehana e hoʻouna i nā loli.
● Ke kolu o ka hanauna
A ma hope o ka hoʻohui ʻana HOOLAHA و IXFR a me nā mea hou e pono ai, ua hoʻomaka ka hoʻomohala ʻana i kahi protocol pākuʻina kau I ka hāʻule ʻana, ʻoiai ua hoʻohui ʻia ke code ma aneʻi, akā ʻaʻohe mea nāna i hāʻawi i nā kuʻina i kahi loiloi maikaʻi o ka mea i kapa ʻia he pono paʻa, ke kia o ka hoʻomohala ʻana i ka hanauna ʻekolu ka palekana. pākuʻina kau A e hoʻomau ia no nā makahiki he nui e hiki mai ana.
Pehea e hana ai kahi kikowaena DNS
E paʻakikī paha ke kaʻina akā hiki ke maʻalahi ʻia ma ka ʻōlelo ʻana i kahi kikowaena pākuʻina kau
ʻO ia ka palapala ʻāina e hana ai ka Pūnaewele ma ke ʻano āu i ʻike ai; ʻOiai, ke hoʻokomo ʻoe i ka inoa o kahi pūnaewele i kāu polokalamu kele pūnaewele, kahi kikowaena pākuʻina kau kuhikuhi iā ʻoe i kahi helu wahi IP kona pololei. Lawe ʻia i mau pae a me nā kikowaena he nui, akā wikiwiki loa ke kaʻina.
I mea e ʻike ai i ke kaʻina hana ma hope o ka hoʻonā ʻana o DNS, he mea nui e ʻike i nā ʻāpana lako ʻokoʻa e pono e hele i kahi nīnau DNS. No kahi pūnaewele pūnaewele ʻike ʻia ka DNS a ʻaʻole koi i kahi pilina mai ka kamepiula o ka mea hoʻohana koe wale no ka noi mua.
He aha nā ʻāpana o DNS?
I DNS, hui pū kekahi mau mea e hoʻopau i kāu noi.
● Pūnaewele DNS
Hiki ke noʻonoʻo ʻia ma ke ʻano he kahu puke e noi ana iā ia e ʻimi no kahi puke kikoʻī ma kahi o ka waihona pākuʻina kau recursor He kuleana no ka hoʻouna ʻana i nā noi hou, kahi e hoʻomaikaʻi ai i ka ʻimi a māʻona i ka mea hoʻohana.
● Pūnaewele inoa
ʻO ia ka ʻanuʻu mua i ka unuhi ʻana a i ʻole ke hoʻoholo ʻana i nā inoa hostable i heluhelu ʻia i nā helu IP.
Hiki ke noʻonoʻo ʻia ma ke ʻano he kuhikuhi ma kahi waihona e kuhikuhi ana i nā papa like ʻole o nā puke; Hiki iā ʻoe ke lawe ma ke ʻano he kuhikuhi i nā pūnaewele ʻē aʻe i kikoʻī ʻia.
● Mea lawelawe inoa kikowaena pae kiʻekiʻe
Kahi kikowaena kikowaena pae kiʻekiʻe (TLD) ma ke ʻano he waihona no nā puke i ka waihona.
ʻO kēia kikowaena inoa ka ʻanuʻu hou aʻe i ka ʻimi ʻana i kahi helu IP kikoʻī, ʻoiai e mālama ana i ka ʻāpana hope o ka inoa o kahi pūnaewele. Eia kekahi laʻana, e ʻōlelo mākou he pūnaewele kā mākou me kahi inoa example.com ʻO ka pae kiʻekiʻe loa (mail.).

ʻO ia ka helu hope loa i ka nīnau o nā kikowaena inoa, a inā loaʻa i ka kikowaena kikowaena inoa i ka moʻo i noi ʻia,
E hoʻihoʻi ia i ka IP address o ka inoa inoa i noi ʻia i Luna Hoʻokele DNS nāna i noi mua.
