Kuyerekeza mayankho

Ngati aliyense resolver amabwerera mfundo imodzi, kusintha kwanu ndi bwino kwambiri. Ngati iwo sagwirizana, ena ndibe kulandira kale cached record.

Ikani ndi kubwezeretsa

Kufalitsa amatsatira TTL ndondomeko ndi angatenge mphindi kuti 48 maola. Re-kuyendetsa kuyang’ana mpaka aliyense resolver amavomereza.

Posintha DNS record - kunyamula tsamba lanu ku malo atsopano, kusinthira MX record, kapena kuwonjezera kutsimikizika kwa TXT - kusinthaku sikungafike kwa aliyense pamodzi. Oyang'anira padziko lonse lapansi amasunga ndalama zakale mpaka kumapeto kwa nthawi, kotero kwa nthawi yanthawi zina oyendayenda amawona mbiri yatsopano ndipo ena amawona kale.

Izi woyang'anira amafunsa ambiri akuluakulu anthu resolvers nthawi imodzi ndi kuyerekezera yankho lawo. Ngati iwo onse anabwerera mfundo imodzi, kusintha kwanu anafalitsa kuzungulira; pamene iwo amasiyana, ena resolvers ndibe kulandira cached kopita. Kodi nthawi yayitali bwanji imangotengera TTL ya record, amene inu anaika pa DNS wanu woyang'anira.

Mafunso ofunsidwa nthawi zambiri

Ndi nthawi yomwe imatenga kusintha kwa DNS kuti ifike ku resolvers onse.Kuti ifike, ena a resolvers akhoza kuyankha kale cached record pomwe ena ali ndi imodzi yatsopano.

Amafunsa mayankho ambiri a anthu - Google, Cloudflare, Quad9, OpenDNS ndi ena - pamodzi ndi zomwe zilipo, kenako amayerekezera mayankho awo. Mayankho ogwirizana amatanthauza kuti kusinthaku kwakula.
