Propagate �i Refresh DNS Cache Mai repede

C�nd film web gazd� la spre alt gazd� serviciu’ a servi sau scimbare art.hot. a servi’ IP adres�, unul de la import consideration la spre a asigura la spre a continua availability de la websites c�min pe a servi, minimum art.hot. centrul ora�ului de la web sites, avoid weird problem� such as po�t� electronic� a lua furnizat la spre fiecare a servi randomly, sau browsing la vechi a servi, is cum rapid DNS (Domain Nume Sistem) voin�� a voi a fi capabil la spre a traduce sau resolve hostname sau domain nume into al t�u nou IP adres�, �n schimbul art.hot. vechi IP destina�ie. Unfortunately, webmasters have limitat capacitate la spre contract sau override art.hot. DNS propagation proces. Nonetheless, acolo e�ti lini�tit ni�te tips, �mecherie �i workarounds that a asigura DNS cache voin�� a voi reflect art.hot. nou IP adresat la c�t mai cur�nd posibil.

DNS works �n�untru such as un way that c�nd un a cere pentru IP adres� primit by DNS resolver, it voin�� a voi apoi atunci �ntrebare art.hot. root a servi la spre afl� art.hot. authoritative a servi cu detailed knowledge de la specific domain nume. Dac� un valid IP adres� pentru art.hot. domain is �ntoarcere by art.hot. authoritative a servi, art.hot. DNS resolver voin�� a voi cache art.hot. DNS resolution pentru un a da perioad� de timp known as TTL ( timp La spre Ficat) dup� un victorios answer, �n�untru ce known as DNS caching �n�untru ordine la spre reduce art.hot. load on specific DNS a servi. DNS caching allows resolution de domain nume la spre IP la spre a lua place local folosire art.hot. cached informa�ii �n schimbul �ntrebare art.hot. remote a servi pentru subsequent requests, p�n� la art.hot. TTL duration expires.

Art.hot. Timp- La spre- Ficat (TTL) timp is art.hot. �mecherie la spre a asigura that art.hot. DNS cache expires iute �i always stays proasp�t. TTL is defined by domain administrator �n authoritative DNS a servi pentru art.hot. regiune unde date originates, �i s�u values a instrui DNS caching resolvers la spre expire �i a descoperi art.hot. DNS �nregistr�ri dup� TTL secund�. Inferior art.hot. TTL value voin�� a voi enable rapid expiration �i refreshing de DNS �nregistr�ri, veninos art.hot. nou �nregistr�ri la spre propagate mai repede vizavi art.hot. lume. Totu�i, art.hot. �mecherie nevoie art.hot. nume resolvers a urma art.hot. RFC standards, care most a face. Beside, tu musta�� have plin contract la spre modify art.hot. nume a servi authoritative pentru al t�u domains.

Art.hot. tweaking de TTL �n�untru DNS �nregistr�ri musta�� a fi done c�teva zile �nainte s�u’ despre la spre scimbare ( dat� de a servi film sau IP scimbare) la spre a asigura that tot DNS caching resolvers a primi art.hot. nou TTL value �i expires art.hot. vechi lung value. Art.hot. �mecherie voin�� a voi reduce art.hot. TTL �n�untru anticipation de la scimbare la spre minimum inconsistency �n timpul art.hot. scimbare, acordeon la spreRCF 1034.

TTL is defined by Minimum field �n�untru SOA ( scrobeal� de Autor) tip as lips� TTL, sau individually la each a nota as TTL. RCF 1912 describes art.hot. Minimum field �n�untru details as sub:

minimum Art.hot. lips� TTL ( timp- la spre- ficat) pentru resource �nregistr�ri (RR) — cum lung date voin�� a voi remain �n�untru alt nameservers’ cache. ([RFC 1035] defines this la spre a fi art.hot. minimum value, numai a servi seem la spre always implement this as art.hot. lips� value) Acesta este by departe art.hot. most import timp. A ezat a aranja this as mare as is comfortable a da cum often tu update al t�u nameserver. Dac� tu avion la spre a face major scimbare, s�u’ un bun idea la spre nap this value jos temporarily beforehand. Apoi atunci a�teptare art.hot. previous minimum value, a face al t�u scimbare, verify lor correctness, �i nap this value spate sus. 1-5 days e�ti typical values. A-�i aminti this value a putea a fi overridden on individual resource �nregistr�ri.

Dac� al t�u’ folosire un web- baz� sau grafic user interface la spre conducere al t�u domains’ DNS �nregistr�ri, apoi atunci login la sistem, �i a redacta art.hot. SOA �nregistr�ri. Interior tu vei a vedea un field numit Minimum, modify art.hot. value la spre as low as posibil ( �n�untru secund�), such as 300 pentru timp fiecare 5 minutes. Apoi atunci modify art.hot. TTL pentru tot de la Un, MX, CNAME, TXT, SOA, PTR �i alt �nregistr�ri, dac� cerere.

Dac� tu e�ti folosire cPanel WebHost Conduc�tor (WHM), login �i a alege A redacta DNS Regiune jos DNS Func�ie section. Select art.hot. cerere regiune (domain nume). Tu vei a fi presented cu un list� de �nregistr�ri. Modify art.hot. minimum ttl �n�untru SOA, �i TTL Columbia de Un, MX, CNAME �i alt �nregistr�ri defined.

Pentru aceia manual configure art.hot. authoritative nameserver pentru un domain regiune folosire BIND, modification has la spre a fi done �n regiune dosar. Pentru example, so domain regiune example.com, tu vei a vedea art.hot. a urma resource �nregistr�ri �n regiune dosar:

; regiune 'example.com' TTL$ 14400 
@ �N�UNTRU SOA ns1.example.com. host.example.com. ( 2007080501 ; Serial 10800 ; Refresh 3  or� 3600 ; Retry 1  or�604800 ; Expire 1  s�pt�m�n�86400 ); Minimum 24  or� 
@ NS ns1.example.com.
@ NS ns2.example.com.

@ UN 192.168.0.1 @ MX 10 mail.example.com.

; nameservers ns1 UN 192.168.0.11 ns2 UN 192.168.0.12 ; po�t�  a servi po�t�  UN 192.168.0.10 ; web  a servi www CNAME example.com.

Acum scimbare art.hot. TTL$ 14400 cu art.hot. value tu nevoie ( �n�untru secund�), such as 300 (5 minutes). This value defines art.hot. lips� TTL de tot existing �nregistr�ri, �i by inferior this value la spre 300 ( pentru example, tu po�i a alege al t�u won value), caching a servi voin�� a voi a fi �inere this �nregistr�ri pentru mai mult dec�t 5 minutes �nainte �ntrebare art.hot. authoritative nume a servi care voin�� a voi a fi art.hot. primul la spre reflect art.hot. nou IP adres� c�nd scimbare mai t�rziu on iar. Alt value that tu trebiue scimbare is minimum TTL, art.hot. ultimul linie de SOA tip (remarked as minimum 24 or�).

Dup� scimbare, al t�u DNS regiune dosar voin�� a voi probably arat� ca this:

; regiune 'example.com' $TTL 300 
@ �N�UNTRU SOA ns1.example.com. host.example.com. ( 2007080501 ; Serial 10800 ; Refresh 3  or� 3600 ; Retry 1  or�604800 ; Expire 1  s�pt�m�n�300 ); Minimum 24  or� 
@ NS ns1.example.com.
@ NS ns2.example.com.

@ UN 192.168.0.1 @ MX 10 mail.example.com.

; nameservers ns1 UN 192.168.0.11 ns2 UN 192.168.0.12 ; po�t�  a servi po�t�  UN 192.168.0.10 ; web  a servi www CNAME example.com.

Pauz� art.hot. DNS serviciu. Art.hot. nou TTL value voin�� a voi propagate la spre alt DNS nameserver. This proces typically a lua 48 or� la spre 72 or� (hence art.hot. nevoie la spre reduce TTL la spre try la spre a face it mai repede c�nd scimbare art.hot. critical UN �i MX �nregistr�ri). Dup� a�teptare pentru c�teva zile, a mi�ca al t�u websites la spre nou a servi sau scimbare art.hot. IP adres�, �i apoi atunci update art.hot. DNS �nregistr�ri la spre point la nou a servi sau IP.

O dat� done, tu po�i acum revers spate art.hot. TTL values la spre reduce art.hot. load on al t�u DNS a servi.
