Cov lus teb luv luv: yog xav xyuas cov ntaub ntawv DNS hauv online, sau koj lub npe rau hauv PromoPilot's DNS Lookup thiab nyem "Tshawb Xyuas." Lub cuab yeej yuav nug koj lub DNS thiab tso saib txhua hom ntaub ntawv tseem ceeb—A, AAAA, CNAME, MX, NS, TXT, SOA, SRV—nrog rau lawv cov nqi TTL. Nws pub dawb thiab tsis tas yuav sau npe. Hauv qab no koj yuav pom lub ntsiab lus ntawm txhua cov ntaub ntawv, yuav nyeem cov txiaj ntsig li cas, thiab cov yuam kev feem ntau uas ua rau cov vev xaib thiab email puas tom qab tsiv chaw.
DNS yog qhov "tsis pom" tshaj plaws ntawm lub vev xaib: tsuav yog txhua yam ua haujlwm, tsis muaj leej twg xav txog nws. Tab sis thaum tus neeg siv khoom yws tias "lub xaib tsis qhib" lossis "cov email tsis tau xa tuaj," thawj qhov kuv ua yog xyuas cov ntaub ntawv sau npe - hauv ib nrab ntawm cov rooj plaub, qhov ntawd yog qhov teeb meem nyob.
Kev kuaj xyuas cov ntaub ntawv DNS qhia dab tsi?
Txhua cov ntaub ntawv DNS teb nws cov lus nug: lub vev xaib nyob qhov twg, leej twg tau txais email, leej twg tswj hwm thaj chaw. Cov cuab yeej sau lawv ua ib daim ntawv qhia.
| Hom ntaub ntawv | Txhais li cas? | Piv txwv ntawm lub ntsiab lus | Yog muaj qhov yuam kev ces yuav tawg li cas? |
|---|---|---|---|
| Ib | Chaw nyob IPv4 ntawm lub vev xaib server | 203.0.113.10 | Lub xaib tsis qhib lossis qhib rau lwm tus neeg lub server. |
| AAAA | Chaw nyob IPv6 ntawm tus neeg rau zaub mov | 2001:db8::10 | Lub xaib tsis qhib rau qee lub network mobile. |
| CNAME | Lub npe menyuam yaus ntawm lwm lub npe | www → example.com | Lub subdomain taw tes rau qhov chaw tsis raug |
| MX | Cov servers xa ntawv thiab lawv qhov tseem ceeb | 10 mail.example.com | Cov ntawv tsis tuaj txog |
| NS | Cov servers uas tswj hwm thaj chaw | ns1.provider.net | Tag nrho lwm cov ntawv nkag raug tsis quav ntsej. |
| TXT | Cov ntaub ntawv sau: SPF, kev lees paub kev pabcuam | v=spf1 include:… ~all | Cov email yog spam, kev pabcuam tsis tau txheeb xyuas |
| SOA | Cov Ntaub Ntawv Kev Pabcuam Cheeb Tsam: Tus Neeg Pabcuam Tseem Ceeb, Tus lej Serial | ns1.provider.net … | Lus Cim: Puas yog thaj chaw hloov tshiab? |
| SRV | Cov chaw nyob rau kev pabcuam: xov tooj, cov neeg xa xov tam sim ntawd | _sip._tcp … | Cov kev pabcuam tsis txuas nrog |
Txhua cov ntaub ntawv muaj TTL - tus naj npawb ntawm vib nas this uas lwm cov servers tuaj yeem khaws cia. TTL txiav txim siab seb cov kev hloov pauv sai npaum li cas rau cov neeg tuaj saib. Koj tuaj yeem tshawb xyuas txhua lub npe - koj tus kheej, tus neeg cog lus, lossis tus neeg sib tw: Cov ntaub ntawv DNS yog pej xeem.
Yuav ua li cas los xyuas cov ntaub ntawv DNS ntawm ib lub npe hauv online?
- Qhib lub cuab yeej. DNS Lookup khiav hauv koj tus browser.
- Sau lub npe sau tsis muaj tus txheej txheem:
example.com, tsis yoghttps://example.com/. - Xaiv hom ntaub ntawv —A, MX, NS, TXT, thiab lwm yam — lossis saib lawv tag nrho ib zaug.
- Nyem "Tshawb xyuas" thiab tshuaj xyuas cov ntawv nkag pom thiab lawv lub ntsiab lus.
- Piv rau qhov nws yuav tsum yog: IP los ntawm lub vaj huam sib luag hosting, MX los ntawm cov lus qhia ntawm kev pabcuam xa ntawv.
- Kho cov ntaub ntawv uas thaj chaw raug tswj hwm (qhov no pom tau los ntawm NS) thiab rov xyuas dua.
Cov nplooj ntawv cuab yeej muaj ib daim teb rau lub npe sau, ib lub pob pov thawj, ib qho lus piav qhia luv luv, thiab ib lo lus teb rau lo lus nug "DNS yog dab tsi?"
Cov lus qhia tseem ceeb: xyuas NS ua ntej. Yog tias lub npe sau tau muab rau cov servers hosting, thiab koj hloov kho cov ntaub ntawv ntawm tus neeg sau npe, cov kev hloov pauv yuav tsis muaj txiaj ntsig - tsis muaj leej twg yuav nyeem lawv.
Yuav nyeem qhov tshwm sim li cas thiab yuav kho dab tsi ua ntej?
Cov yuam kev DNS yuav luag tshwm sim tib lub sijhawm: hloov chaw hosting, hloov chaw sau npe mus rau lwm tus neeg sau npe, lossis txuas mus rau email lossis CDN. Nov yog yuav ua li cas los xyuas:
- NS taw qhia rau qhov chaw koj hloov kho thaj chaw. Qhov no yog thawj qhov tseem ceeb tshaj plaws. Kev hloov kho hauv vaj huam sib luag "yuam kev" yog qhov laj thawj feem ntau rau cov kab lus "Kuv tau hloov txhua yam, tab sis tsis muaj dab tsi ua haujlwm."
- Cov ntaub ntawv A taw tes rau lub server tam sim no. Tom qab tsiv mus, tus IP qub feem ntau tseem nyob ntawm lub hauv paus sau npe lossis ntawm
www. Xyuas ob lub npe. - Tsis muaj kev sib cav sib ceg ntawm CNAME. Ib lub npe sau tsis tuaj yeem muaj ob qho tib si CNAME thiab lwm cov ntaub ntawv. Yog tias
wwwyog CNAME, nws yuav tsum tsis txhob muaj nws cov ntaub ntawv A. - Cov ntaub ntawv MX taw qhia rau qhov kev pabcuam email uas koj xav tau. Ob daim ntaub ntawv MX "qub" thiab ib daim "tshiab" yuav ua rau cov email ploj mus yam tsis tau npaj tseg.
- TXT: Ib daim ntawv teev npe SPF rau ib lub npe sau. Ob daim ntawv teev npe
v=spf1yog qhov yuam kev ntau tom qab txuas rau qhov kev pabcuam xa ntawv thib ob. Lawv yuav tsum tau muab tso ua ke ua ib qho. - AAAA tsis ua rau tsis muaj dab tsi li. Yog tias tus neeg muab kev pabcuam hosting hloov pauv tab sis cov ntaub ntawv AAAA qub tseem nyob, qee tus neeg tuaj xyuas IPv6 yuav xaus rau ntawm lub server qub.
Yuav ua li cas tswj TTL thaum lub sijhawm tsiv teb tsaws chaw: 24 teev ua ntej IP hloov, txo A-record TTL mus rau 300 vib nas this. Ua li no, tom qab hloov, tus nqi qub yuav ploj ntawm cov caches hauv tsib feeb es tsis yog 24 teev. Thaum txhua yam ua haujlwm zoo, TTL tuaj yeem rov pib dua mus rau 3600 lossis siab dua.
Nov yog qhov chaw noj qab haus huv, tsawg kawg nkaus ntawm lub vev xaib me me nrog email zoo li cas hauv kev pabcuam sab nraud - nws yooj yim rau kev sib piv koj daim ntawv qhia rau nws:
example.com. 3600 A 203.0.113.10
www.example.com. 3600 CNAME example.com.
example.com. 3600 MX 10 mx1.mailprovider.net.
example.com. 3600 MX 20 mx2.mailprovider.net.
example.com. 3600 TXT "v=spf1 include:_spf.mailprovider.net ~all"
_dmarc.example.com. 3600 TXT "v=DMARC1; p=quarantine"
Ib qho chaw nyob IP rau lub xaib, www ua lub npe cuav, ob daim ntawv MX nrog cov kev xaiv sib txawv (tus lej qis dua yog lub server tseem ceeb), thiab ib daim ntawv SPF. Txhua yam dhau qhov no yuav tsum muaj lub hom phiaj meej: kev txheeb xyuas Google Search Console, cov ntaub ntawv CDN, thiab DKIM.
Thiab ib qho ntxiv txog SOA. Nws muaj tus lej zone serial: yog tias nws tsis tau hloov tom qab kev hloov kho, nws txhais tau tias cov kev hloov kho tsis tau tshaj tawm - lossis koj tau hloov kho thaj chaw tsis raug.
