DNS vs DDNS
DNS thiab DDNS yog cov txheej txheem kev cai suav nrog TCP / IP. DNS txhais tau tias Domain Name System hos DDNS txhais tau tias Dynamic Domain Name System. Vim tias cov neeg siv tsis tuaj yeem nco qab tus lej IP chaw nyob ntawm cov vev xaib sib txawv uas yog vim li cas Domain Name System tau tsim.
Domain Name System
DNS yog txheej txheej txheej txheem suav nrog TCP / IP. DNS pab thiab DNS tus thov kev pab yog ob qho software uas tau siv los siv Domain Name System thiab ob qho ntawm cov software no khiav ntawm keeb kwm yav dhau.
Tus lej IP chaw nyob yog siv los txheeb xyuas cov peev txheej hauv network. Txawm li cas los xij, nws nyuaj rau cov neeg siv network kom nco qab cov lej IP chaw nyob. Cov ntaub ntawv hauv DNS sau cov npe alphanumeric rau txhua qhov kev pabcuam hauv network sib raug rau IP chaw nyob ntawm cov vev xaib sib txawv. Cov npe alphanumeric no yog cov neeg siv tus phooj ywg. Qhov no ua rau cov peev txheej hauv network nco tau yooj yim los ntawm cov neeg siv network.
Tus DNS neeg rau zaub mov thiab cov neeg siv khoom muab los ntawm Microsoft hauv Windows Server 2003 siv DNS raws tu qauv uas siv hauv TCP?IP raws tu qauv suite. Hauv TCP / IP tus qauv siv, DNS nyob ntawm daim ntawv thov txheej.
Hauv lub network uas muaj Windows Server 2003, lub npe sau npe siv rau txhua hom kev daws teeb meem lub npe. Thaum Windows server 2003 tus neeg siv qhia lub npe ces tus neeg rau zaub mov hu rau DNS server txhawm rau daws cov npe uas sib haum rau IP chaw nyob ntawm lub vev xaib.
Dynamic Domain Name System
Muaj qee lub khoos phis tawj uas hloov lawv qhov chaw nyob IP nquag. Tshwj tsis yog tias koj lub vev xaib tsis hloov nrog qhov chaw nyob IP, qhov no tsis yog qhov teeb meem txhua.
Txawm li cas los xij, Dynamic DNS siv los txhawm rau zam qhov xwm txheej no. Siv cov txheej txheem no, lub vev xaib lossis lub vev xaib tuaj yeem tswj tau yooj yim thiab tsis tas yuav txhawj xeeb tias lwm tus neeg siv yuav tsis tuaj yeem nkag mus rau nws.
Txhua lub sijhawm koj txuas rau Is Taws Nem, tus IP chaw nyob ib ntus raug muab rau koj lub tshuab los ntawm Tus Muab Kev Pabcuam Hauv Is Taws Nem. Qhov no kav mus txog rau thaum koj disconnect los ntawm internet. Hauv qhov xwm txheej, yog tias koj hloov kho koj lub vev xaib thaum lub sijhawm sib tham hauv is taws nem ces tus IP chaw nyob ntawm lub vev xaib tseem yuav hloov pauv. Kev taug qab ntawm koj lub vev xaib yuav nyuaj rau cov khoos phis tawj uas tsis tau nruab.
Txawm li cas los xij, qhov no yuav raug saib xyuas los ntawm Dynamic DNS uas hloov pauv tus IP chaw nyob ntawm koj lub vev xaib sib raug. Yog li, tus neeg uas xav nkag mus rau koj lub vev xaib tsis tas yuav tsum ntaus tus IP chaw nyob ntawm koj lub vev xaib.
Lub Dynamic DNS tuaj yeem ua rau hauv daim ntawv kho vajtse ntawm software. Routers thiab lwm yam kev sib txuas lus muaj xws li kho vajtse ib feem ntawm dynamic DNS.
Ceebtoom: DNS system tuaj yeem siv tau hauv intranet nrog rau tus IP chaw nyob tus kheej.
Qhov txawv ntawm DNS thiab DDNS:
• DNS yog qhov zoo li qub uas txhais tau tias nws tseem nyob ruaj khov rau ib qho tshwj xeeb thaum Dynamic DNS hloov pauv yog qhov hloov pauv uas txhais tau tias nws hloov txhua lub sijhawm.
• Ob lub tshuab suav nrog TCP / IP raws tu qauv.
• Ob DNS thiab DDNS yog tsim los vim cov neeg siv tsis tuaj yeem nco qab tus lej IP chaw nyob ntawm cov vev xaib sib txawv.
