Setlhatlhobi sa DNS
Tsenya leina la domeine go tsaya rekoto nngwe le nngwe ya DNS e e e phasalatsang — diaterese (A, AAAA), maina a a sa tlwaelegang (CNAME), tsela ya poso (MX), disefara tsa maina (NS), ditlhangwa tsa netefatso (TXT) le dipholisi tsa tshireletso (CAA, SOA).
Se mofuta mongwe le mongwe wa rekoto ya DNS o se kayang
Tsamaiso ya Leina la Domain e boloka go le gontsi go feta aterese ya domeine. Setlhatlhobi seno se botsa DNS e e tshelang ka DNS-over-HTTPS e e tsenngwang khoutu mme se bega mofuta mongwe le mongwe wa rekoto o kgolagano ya dikhomphiutha e o gatisang:
- A / AAAA - IPv4 / IPv6 diaterese tsa domain domain ho. Kwantle ga bobotlana nngwe ya tseno, kgolagano ya dikhomphiutha ga e ka ke ya amogela webosaete.
- CNAME — leina le lengwe le le supang leina le lengwe mo go le lengwe. Ga e letlelelwe mo ntlheng ya kgaolo, ka jalo example.com ka tlwaelo ga e kitla e bontsha epe.
- MX — disefara tsa imeile tse di amogelang imeile ya domeine, nngwe le nngwe e na le se se tlang pele. Ga go na MX gantsi go raya gore ga go na imeile.
- NS — di-server tsa leina tse di nang le taolo tse di arabelang kgaolo.
- TXT — mongolo wa sebopeho se lokolohileng: dipholisi tsa SPF tse kgahlano le ho qhekella, ho saena ha DKIM (di-subdomain), dithokene tsa netefatso ya beng ba domain.
- CAA — ke balaodi bafe ba ba letleletsweng go ntsha disetifikeiti tsa TLS tsa domeine.
- SOA — metadata ya tsamaiso ya kgaolo: sefara ya leina la konokono, di-timers tsa go ikgolaganya le tsa go boloka.
Ke eng o tlhola direkoto tsa DNS?
- Morago ga go fuduga kgotsa go tseleganya DNS — netefatsa gore direkoto tse dišwa di tshela mo ditharabololong tsa setšhaba, e seng fela mo polokelotshedimosetsong ya khomphutha ya gago.
- Go romelwa ga imeile — netefatsa gore ditsenngwa tsa SPF/MX di nepagetse pele melaetsa e simolola go boa.
- Ditshekatsheko tsa tshireletsego — bona diphetogo tse di sa lebelelwang tsa TXT/NS, mme o netefatse gore CAA e kwala fela di-CA tse o di dirisang.
Kgakololo: Diphetolo tsa DNS ga di tlhagelele ka bonako gongwe le gongwe — TTL ya rekoto nngwe le nngwe e bolelela ba ba rarabololang gore ba boloke karabo ya bogologolo lobaka lo lo kana kang. Fokotsa TTL pele ga phetogo e e rulagantsweng, o bo o e tlhatlosa gape morago ga moo.
A o bone diaterese? Bona Domain go ya go IP go bona porofaele e e feletseng ya go amogela aterese, dirisa tlhotlhomiso ya lenaane le lentsho mo go yone, kgotsa buisa busetsa DNS kwa morago.
Dipotso tsa setlhotlhomisi sa DNS
Setlhatlhobi sa DNS ke eng?
Motlhatlhobi wa DNS o botsa Tsamaiso ya Leina la Domain ka mofuta mongwe le mongwe wa rekoto ya domain — diaterese tse e di supang (A, AAAA), disefara tsa yone tsa poso (MX), disefara tsa maina (NS), dikgwele tsa netefatso (TXT) le dipholisi tsa tshireletso (CAA) — mme o bega sentle se se gatisitsweng.
Ke eng ke sa kgone go bona rekoto ya CNAME ya modi wa kgolagano ya dikhomphiutha ya me?
DNS ga e letle CNAME mo ntlheng ya kgaolo (example.com ka boyone) — modi o tshwanetse go dirisa direkoto tsa A/AAAA. Direkoto tsa CNAME di tlhagelela fela mo dikarolwaneng tse di jaaka www.sekai.com.
Diphetogo tsa DNS di tsaya lobaka lo lo kana kang go bonala?
Rekoto nngwe le nngwe e na le TTL (nako ya go tshela) e e bolelelang ba ba rarabololang gore ba e boloke lobaka lo lo kana kang — go tswa go metsotswana go ya go malatsi. Morago ga go rulaganya rekoto, bararabolodi ba setšhaba ba nna ba direla karabo ya bogologolo go fitlha TTL ya yone e fela, ka jalo go anamisiwa go ka tsaya lobaka lo loleele jaaka TTL e e fetileng.
