Iyo Domain Name System (DNS) inoshandura nzvimbo yeInternet uye mazita ekutambira kuIndaneti uye pamwe chete.
PaIndaneti, DNS inotendeuka pachayo pakati pemazita atinonyora muwebhu rebhundaneti rebar address kuIndaneti dzemaseva eWebhenji anobata nzvimbo idzi. Makambani makuru makuru anoshandisa DNS kuti atarisire yekambani yavo intranet . Mishandisirwo emunharaunda anoshandisa DNS apo iwe unoshandisa Indaneti asi usashandise kugadzirisa mazita emakombiyuta epamba.
Nzira DNS Inoshanda Sei?
DNS ndeyo muteresi / server network network communication: DNS vatengi vanotumira zvikumbiro uye vanogamuchira mhinduro kubva kumaseva eDNS . Zvikumbiro zvine zita, izvo zvinoguma nekero re IP rinodzorerwa kubva kune seva, rinonzi mberi DNS lookups. Zvikumbiro zvine rine kero ye IP uye zvinokonzera zita, zvinonzi reverse DNS lookups, zvinotsigirwa zvakare. DNS inoshandisa dhiyabhorosi yakachengetedzwa kuchengetedza zita iri uye ruzivo rwekupedzisira rwekero yekero yevanhu vose vanogara paIndaneti.
DNS database inogara pane hutungamiri hwemaseri epa database. Apo vashandi vanoita seWeb browser vanoshandisa zvikumbiro zvinosanganisira mazita eIndaneti, chidimbu chepurogiramu (inowanzovakwa mumutambo wekushanda) inonzi DNS resolver kutanga inosangana neDNS server kuti ione IP ye server. Kana DNS server isina mapikicha anodiwa, ichazoendesa mberi kune chikumbiro kune imwe DNS server pane imwe yakakwirira yepamusoro muhutungamiri. Mushure mokunge kune dzimwe nzira dzakatumira uye nhume dzakatumirwa dzinotumirwa mukati mehutano hweDNS, kero ye IP yevakapiwa mupiro inozopedzisira yasvika pa resolver, iyo inopedzawo chikumbiro paInternet Protocol .
DNS inowedzera inosanganisira kutsigirwa kwekukumbira kwekuchengetedza uye kuburitsa . Nenzira dzakawanda masangano ekushandisa anotsigira kugadziriswa kwemaseri ekutanga, echipiri, uye epamusoro DNS, imwe neimwe inogona kushanda zvikumbiro zvekutanga kubva kune vatengi.
Kugadzirisa DNS paMafungiro eMunhu neKumba Network
Internet Service Providers (ISPs) vanochengetedza maDNS server avo uye vanoshandisa DHCP kuti vakwanise kugadzirisa mitambo yevatengi vavo, Automatic DNS server basa inoderedza mhuri dzekutakura kweDNS configuration. Home network vatungamiri havakwanisi kuchengetedza zvirongwa zvavo zveIPs, zvisinei. Vamwe vanosarudza kushandisa imwe yeiyo inowanika yepaIndaneti DNS services panzvimbo. Zvose zveDNS services zvakagadzirirwa kupa hutano huri nani nekuvimbika pane izvo zvinowanzoitwa ISP zvinogona kupa.
Mhuri broadband routers nemamwe magetsi masuo magetsi mashamba ekutanga, secondary uye epamusoro DNS server IP mazita emusangano uye anovapa kumakambani emafoni sezvaanoda. Vatungamiri vanogona kusarudza kuisa maateri nemaoko kana kuawana kubva kuDHCP. Mazwi anogona zvakare kuongororwa pane imwe kambani yeklayiti kuburikidza nemashandisi ayo ekugadzirisa menyu.
Nyaya dzine DNS dzinogona kuva pakati nepakati uye zvakaoma kutambudza zvakapiwa zvisikwa zvayo. Vatengi vanogona kuramba vachibatanidza kumatare avo emunharaunda apo DNS inoputsika, asi havazokwanise kusvika kumakamuri ekuma mazita avo. Apo mitambo yekugadzirwa kwekambani yemaklayiti inoratidza DNS server mazita e 0.0.0.0 , inoratidza kusakatika neDNS kana nekugadzirisa kwayo panzvimbo yekero.
