DNS Name Name System (DNS) ikutanthauzira ma intaneti ndi maina apamtunda ku ma intaneti ndipo mosiyana.
Pa intaneti, DNS imasinthira pakati pa maina omwe timasankha pa barreji yathu ya osatsegula pa Webusaiti ku ma intaneti a ma seva a pa Intaneti omwe akugwiritsira ntchito malowa. Makampani aakuluakulu amagwiritsanso ntchito DNS kusamalira intranet yawo . Ma intaneti amagwiritsira ntchito DNS pamene akulowa pa intaneti koma osagwiritsa ntchito kuyang'anira mayina a makompyuta a kunyumba.
Momwe DNS Imachitira
DNS ndi machitidwe a kasitomala a kasitomala / otumizirana mauthenga: DNS makasitomala amatumiza zopempha kuti alandire mayankho kuchokera kwa amaseva a DNS . Zopempha zili ndi dzina, zomwe zimachititsa kuti adilesi ya IP abwerere kuchokera ku seva, akutchedwa kuti DNS lookups. Zopempha zomwe zili ndi adilesi ya IP ndipo zimakhala ndi dzina, lotchedwa reverse DNS lookups, zimathandizidwanso. DNS imagwiritsa ntchito mndandanda wa masamba kusungira dzina ili ndi mauthenga odziwika a adiresi kwa makamu onse a pa Intaneti pa intaneti.
DNS yachinsinsi imakhala pa maudindo apadera apadera ma database. Pamene makasitomala ngati Mawebusaiti a Webusaiti akupempha zophatikizapo maina a intaneti, chidutswa cha pulogalamu (yomwe nthawi zambiri imagwiritsidwa ntchito mu intaneti) yotchedwa DNS resolver yoyamba kulankhulana ndi seva ya DNS kudziwa malo a IP seva. Ngati seva ya DNS ilibe mapu oyenera, idzaperekanso pempho kwa adiresi yosiyana ya DNS pamlingo wapamwamba wotsatirayi. Pambuyo pa mauthenga angapo opititsa patsogolo ndi nthumwi atumizidwa mkati mwa maudindo a DNS, adilesi ya IP ya wolandiridwayo potsirizira pake amafika pa resolver, yomwe imamaliza pempho la Internet Protocol .
DNS yowonjezerapo ikuphatikiza chithandizo kwa zopempha za caching ndi redundancy . Machitidwe ambiri ogwiritsira ntchito makompyuta amathandizira kukonza ma seva a DNS apamwamba, apamwamba, ndi apamwamba, omwe aliwonse angathe kuthandiza opempha zoyambirira kuchokera kwa makasitomala.
Kuika DNS pa Zipangizo Zamwini ndi Ma Network Home
Othandiza Atumiki a intaneti (ISPs) amasunga ma seva awo a DNS ndipo amagwiritsa ntchito DHCP kukhazikitsa makina awo a makasitomala, Ntchito yaSeva ya DNS yokhayokha imathandizira mabanja kulemetsa kwa DNS kukonza. Olamulira a pa intaneti sakufunika kuti asunge ma ISPs awo, komabe. Ena amakonda kugwiritsira ntchito limodzi la misonkhano ya pa Intaneti DNS m'malo mwake. Mapulogalamu a DNS a anthu apangidwa kuti apereke ntchito yabwino ndi kudalirika pa zomwe ISP imatha kupereka.
Mayendedwe apakompyuta a kunyumba ndi makina ena osungirako zipangizo zamakono apamwamba, apamwamba ndi apamwamba adiresi ya IP DNS maadiresi a pa intaneti ndi kuwapereka kwa makasitomala zipangizo monga pakufunikira. Olamulira angasankhe kulowa maadiresi pamanja kapena kuwapeza kuchokera ku DHCP. Maadiresi amatha kusinthidwa pa chipangizo cha makasitomala kudzera m'masitimu okonzekera.
Nkhani zomwe zili ndi DNS zikhoza kukhala zosasinthasintha ndipo zovuta kuthetsa zimapereka chilengedwe chake. Otsatsa angathe kugwirizana ndi makina awo apakompyuta pamene DNS yathyoledwa, koma sangathe kufika kuzipangizo zakutali ndi dzina lawo. Pamene makonzedwe a makanema a chipangizo cha kasitomala amasonyeza ma Adresse a seva a DNS a 0.0.0.0 , amasonyeza kulephera ndi DNS kapena kukonzekera pa intaneti.
