Ka Buke Helu o ka Pūnaewele
ʻO kaʻili pūnaewele a me nā pūnaewele pūnaewele'Ilepa nui nui (IP) e hilinaʻi ana i ka hilinaʻiʻana i ka System Domain System (DNS) e kōkua i ke kaʻa pololei. Ke mālama nei ka DNS i kahiʻikepili i hoʻokaʻawaleʻia o nā inoa kikowaena a me nā address, a hāʻawiʻia i nā ala no nā kamepiula e noi i kaʻikepili wikiwiki. Kapa kekahi poʻe i ka DNS ka "helu phone of the Internet."
DNS a me ka Pūnaewele puni honua
Hiki i nā pūnaewele lehulehu a pau ma luna o nā pūnaewele i pili pū me ka Internet pūnaewele IP . ʻO ka pūnaewele pūnaewele ma About.com, no ka laʻana, loaʻa nā helu e like me 207.241.148.80. ʻOiai hiki i nā kānaka ke hoʻokomo i kaʻikepili o ka helu e like me http://207.241.148.80/ i ko lākou pūnaewele pūnaewele e kipa i nā wahi, hiki iā lākou ke hoʻohana i nā inoa kūpono e like me http://www.about.com/.
Hiki i ka Pūnaewele hoʻohana i DNS ma keʻano he laha hoʻonā inoa no nāʻena pūnaewele. Ke waiho kekahi i kahi inoa o ka pūnaewele i kā lākou polokalamu kele pūnaewele, e nānā anaʻo DNS i ka IP address e pili ana no kēlā pūnaewele, nāʻike i makemakeʻia e hoʻohui i nā pūnaewele i makemakeʻia ma waena o nā pūnaewele pūnaewele a me nā pūnaewele pūnaewele .
DNS Servers a me ka inoa inoa
Hoʻohana ka DNS i kahi hoʻolālā pūnaewele kahu / server . ʻO nā kikowaena DNS he papahana i hoʻonohonohoʻia no ka mālamaʻana i nā pūnaeweleʻikepili DNS (nā inoa a me nā wāwae), akāʻo nā mea kūʻai o ka DNS nā PC, nā leka a me nā meahana'ē aʻe o nā mea hoʻohana. Nūnā pūnaewele DNS pū kekahi me kekahi, e hana ana i nā mea kūʻai i kekahi i ka wā e pono ai.
Kūkulu ka DNS i kāna mau kiko i kahi hiʻona. No ka pūnaewele, kapaʻia ka inoa o ka pūnaewele inoa inoa ma kahi kiʻekiʻe o ke kūlana DNS. Mālama ka inoa o ka pūnaewele hōʻoia i nāʻikepili DNS no nā kikowaena kiʻekiʻe o ka pūnaewele (TLD) (like ".com" a me ".uk"), kahi inoa a me nā inoa IP o nā'atihana DNS (i kapaʻia he mana ) DNS mauka no ka paneʻana. nā nīnau e pili ana i kēlā me kēia TLD maʻamau. Nā Servers ma ka lalo lalo o nāʻaoʻao inoa DNS a me kahi mau inoa (e like me "about.com"), a me nā papa'ē aʻe e mālama i nā kikowaena Pūnaewele (e like me "compnetworking.about.com").
Ua hoʻonohonohoʻia a mālamaʻia nā pūnaewele DNS e nāʻoihana pilikino a me nā luna hoʻomalu pūnaewele puni honua. No ka pūnaewele, 13 pūnaewele inoa inoa (nā kumu wai maoli o ka honua) e kākoʻo i nā haneli o nā pūnaewele kiʻekiʻe o ka Pūnaewele,ʻoiai e pili anaʻo About.com i nāʻike o ka pūnaewele DNS no nā pae i loko o kāna pūnaewele. Hiki i nā hui ke hoʻonohonoho pono i ka DNS ma ko lākou mau pūnaewele kikowaena, ma ka liʻiliʻi loa.

Hoʻonohonoho i nā Pūnaewele no ka DNS
Pono nā kimekele DNS (i kapaʻia nā haipule ) e makemake ana e hoʻohana i ka DNS e hoʻonohonohoʻia i kā lākou pūnaewele. E hoʻoholo i ka hulina i ka DNS ma o kahi o nā IP i hoʻopaʻa ( static ) i hoʻokahi aʻoi aku paha o nā kikowaena DNS. Ma kahi pūnaewele home, hiki ke hoʻonohonoho ponoʻia nā inoa o nā kikowaena DNS i hoʻokahi manawa ma kahi pākeke broadband a laweʻia e nā polokalamu kelepona , aiʻole e hoʻopiliʻia nā leka uila ma kēlā me kēia kanaka pākahi. Hiki i nā luna pūnaewele home ke loaʻa nā inoa kikowaena DNS maikaʻi mai ko lākou mea hoʻolaha pūnaewele aiʻole mea hoʻolako pūnaewele hōʻokoʻaʻekolu e like me Google Public DNS a me OpenDNS.

Ua hoʻohana pinepineʻia ka DNS e nā mea pūnaewele pūnaewele i ka hoʻololiʻana i nā inoa o ka pūnaewele pūnaewele i nā koina IP . Ma waho o kēia mau nānā hou , ua hoʻohanaʻia ka DNS no:
- ʻike i nā kikowaena kūpono e lawe i ka leka uila
- Huli i nā huli huli i hoʻololi i kahi IP IP i ka inoa inoa
Nā noi kikoʻa e kākoʻo ana i nā huli DNS ma luna o TCP a me UDP , port 53 ma ke alaʻole.

Kāleka DNS
No ka hoʻoponopono maikaʻiʻana i nā puke kiʻekiʻe o nā noi, nā DNS ke hoʻohanaʻana i ka paleʻana. Paena pūnaewele DNS ma kahi o nā kope o nā pūnaewele DNS i hala koke nei i ka wā e hoʻomauʻia nā hoʻomanaʻo i nā kikowaena i kohoʻia.

Ua hoʻomaka pūʻia nā pale DNS e kū'ē iā lākou ma nā pūnaewele hōʻailona. Hiki i nā luna hoʻonohonoho pūnaewele ke hoʻohemo i kahi pelekane DNS inā pono lākou e hoʻohana i ipconfig a me nā pono hana like.

Dynamic DNS
Ponoʻo DNS e hōʻoia i nāʻikepili IP a pau i mālamaʻia i loko o kaʻikepili e hoʻopaʻa. He hana maikaʻi kēia no ke kākoʻoʻana i nā pūnaewele pūnaewele kūikawā akā,ʻaʻole no nā polokalamu e hoʻohana ana i nā kūmole IP kūlana e like me nā kamepiula pūnaewele pūnaewele a iʻole nā pūnaewele pūnaewele home Hoʻohuiʻo Dynamic DNS (DDNS) i nā hoʻopili kamepiula kikowaena i DNS no ka hoʻonāʻana i ka lawelawe hoʻohauna inoa no nā mea kūʻai ikaika.
Hāʻawi nā mea hoʻolaha i nā lālā likeʻole i nā papa hana DNS ikaika i hanaʻia no ka poʻe e makemake ana eʻae i ke kelepona i kā lākou pūnaewele ma o ka pūnaewele. Hoʻonohonoho i kahi'ānamu DDNS pūnaewele e makemake ana e kākau pū me ka mea i kohoʻia a hoʻomohala i nā pono'ē aʻe ma ka pūnaewele kaiakū. Hoʻomaʻalo pono ka mea mālama DDNS i nā mea i kākau inoaʻia a ke hana nei i nā hōʻoia server server.

ʻO ka Microsoft Windows Internet Naming Service (WINS) ke kākoʻo i ka hoʻohālike inoa e like me DNS akā hoʻohana wale i nā papahana Windows me ka hoʻohanaʻana i kahi kikowaena inoa'ē aʻe. Hoʻohanaʻiaʻo WINS ma kekahi mau kikowaena pūnaewele o nā polokalamu Windows.
ʻO ka Dot-BIT he kumuhana open source e pili ana i kaʻenehana BitCoin e ho'āʻo nei e hoʻohui i kākoʻo no kahi ".bit" top-level domain i ka DNS DNS.
