DDNS stands rau dynamic DNS, los yog, tshwj xeeb tshaj yog, dynamic Domain Name System. Nws yog ib qho kev pabcuam uas qhia cov npe hauv internet sau npe rau IP chaw nyob. Kev pabcuam DDNS cia koj nkag mus rau koj lub computer hauv tsev los ntawm txhua qhov chaw hauv ntiaj teb.
DDNS ua haujlwm zoo ib yam rau hauv Is Taws Nem Lub Npe Lub Npe (DNS) hauv qhov DDNS cia txhua tus uas tuav lub vev xaib lossis FTP server tshaj tawm lub npe pej xeem rau cov neeg siv yav tom ntej.
Txawm li cas los xij, tsis zoo li DNS, uas tsuas yog ua haujlwm nrog IP chaw nyob zoo li qub, DDNS kuj tseem tsim los txhawb kev hloov pauv (hloov) IP chaw nyob, xws li cov uas tau muab los ntawm DHCP server. Qhov ntawd ua rau DDNS yog qhov zoo rau kev sib txuas hauv tsev, uas ib txwm tau txais cov chaw nyob IP ntawm pej xeem los ntawm tus muab kev pabcuam hauv internet.
DDNS tsis zoo ib yam li DDoS, txawm tias cov thev naus laus zis no feem ntau ntawm tib cov ntawv sau.
How a DDNS Service Works
Txhawm rau siv DDNS, kos npe nrog tus kws kho mob DNS dynamic, thiab nruab lawv cov software ntawm lub khoos phis tawj tswj hwm. Lub khoos phis tawj tswj hwm yog lub khoos phis tawj twg siv los ua tus neeg rau zaub mov, yog nws cov ntaub ntawv server, web server, lossis lwm hom server.
Piv txwv li, yog tias koj muaj FTP software ntawm koj lub khoos phis tawj uas hloov lub cuab yeej rau hauv FTP server, nruab daim ntawv thov DDNS ntawm lub khoos phis tawj ntawd. Lub khoos phis tawj ntawd yog qhov uas cov neeg siv ncav cuag thaum lawv thov koj lub server, yog li nws yog qhov uas ib txwm xav tau hloov kho DDNS tus kws kho mob nrog nws qhov chaw nyob IP tam sim no.
Lub software saib xyuas qhov chaw nyob IP dynamic rau kev hloov pauv. Thaum qhov chaw nyob hloov pauv (uas nws thiaj li yuav, los ntawm kev txhais), software hu rau DDNS qhov kev pabcuam los hloov kho koj tus lej nrog tus IP tshiab.
Qhov no txhais tau tias tsuav yog tias DDNS software ib txwm ua haujlwm thiab tuaj yeem kuaj pom qhov hloov pauv hauv IP chaw nyob, DDNS lub npe koj cuam tshuam nrog koj tus lej txuas ntxiv coj cov qhua mus rau tus tswv server txawm tias pes tsawg zaus IP chaw nyob hloov.
A DDNS qhov kev pabcuam tsis tsim nyog rau cov tes hauj lwm uas muaj qhov chaw nyob IP zoo li qub vim tias lub npe sau npe tsis tas yuav paub tias IP chaw nyob yog dab tsi tom qab nws tau qhia thawj zaug ntawm nws thawj zaug. Qhov no yog vim qhov chaw nyob zoo li qub tsis hloov.
A DDNS kev pabcuam tsuas yog ib feem ntawm qhov sib npaug thaum muab cov ntaub ntawv hauv internet los ntawm lub computer. Koj kuj yuav tsum qhia rau lub router uas lub khoos phis tawj ntawm lub network yuav tsum tau hu thaum tus neeg siv sab nraud ntawm lub network nkag mus rau lub server. Qhov no yog ua tiav los ntawm chaw nres nkoj xa mus rau ntawm lub router.
kab hauv qab
A DDNS kev pabcuam zoo meej yog tias koj tuav koj lub vev xaib los ntawm koj lub tsev, muaj cov ntaub ntawv koj xav nkag txawm tias koj nyob qhov twg (xws li cov chaw taws teeb txuas rau koj lub computer thaum koj nyob deb), xav tswj koj lub tsev network nyob deb, los yog lwm yam laj thawj zoo sib xws.
Qhov twg Tau Txais Kev Pabcuam Dawb lossis Them Nyiaj DDNS
Ntau lub chaw muab kev pabcuam online pub dawb DDNS cov kev pabcuam uas txhawb nqa Windows, Mac, lossis Linux computers. Ob peb nyiam suav nrog NoIP, FreeDNS, thiab Dynu.
Nrog DDNS cov kev pabcuam pub dawb, koj tsis tuaj yeem xaiv ib qho URL thiab cia siab tias nws yuav xa mus rau koj lub server. Piv txwv li, koj tsis tuaj yeem xaiv files.google.org ua koj cov ntaub ntawv chaw nyob. Hloov chaw, tom qab xaiv lub npe hostname, koj tau nthuav tawm nrog kev xaiv txwv ntawm cov npe uas koj tuaj yeem xaiv.
Piv txwv li, yog tias koj siv NoIP raws li koj qhov kev pabcuam DDNS, koj tuaj yeem xaiv lub hostname uas yog koj lub npe lossis qee lo lus random lossis sib xyaw ntawm cov lus, xws li my1website, tab sis cov kev xaiv pub dawb yog hopto.org, zapto.org, systes.net, thiab ddns.net. Yog li, yog tias koj xaiv hopto.org, koj qhov DDNS URL yuav yog my1website.hopto.org.
Lwm tus neeg muab kev pabcuam muaj kev xaiv them nyiaj. Google Domains suav nrog kev txhawb nqa DNS dynamic, ib yam nkaus.
