IPv6 hosting hauv kev siv tiag: Kuaj website, DNS, CDN thiab server puas npaj txhij

IPv6 hosting yuav npaj txhij tiag tiag thaum tus neeg siv muaj kev txuas IPv6 uas daws tau lub npe sau npe, teeb tau kev txuas HTTPS thiab rub tau lub vev xaib tag nrho yam tsis ntsib teeb meem. Kev ntxiv ib qho chaw nyob IPv6 lossis tsim ib daim DNS AAAA tshiab tsuas yog thawj kauj ruam xwb. Koj tseem yuav tsum kuaj lub web server, firewall, CDN, email system, daim ntawv thov thiab cov cuab yeej saib xyuas.

Tus qauv uas tsim nyog xaiv tam sim no yog dual-stack: khaws IPv4 thiab IPv6 khiav ua ke es tsis txhob muab IPv4 tshem tam sim ntawd. IPv6 siv chaw nyob ntev 128 bit, hos IPv4 siv chaw nyob 32 bit (raws li IETF). Yog li, lub hom phiaj uas tsim nyog tsis yog “hloov lub vev xaib mus rau IPv6 ib zaug”, tiam sis yog ntxiv ib txoj kev nkag IPv6 uas tswj tau.

IPv6 hosting txawv li cas ntawm IPv4 thiab IPv6 hosting?

Nrog IPv4 thiab IPv6 hosting, tus muab kev pabcuam muab tsawg kawg ib qho chaw nyob IPv4 thiab ib pab lossis ib qho chaw nyob IPv6 uas qhib rau pej xeem rau lub server. Lub vev xaib tuaj yeem nkag tau los ntawm daim A ntawm IPv4 thiab daim AAAA ntawm IPv6. Yog muaj IPv4 xwb, lub vev xaib tseem ua haujlwm rau cov neeg siv feem coob, tiam sis tsis tuaj yeem pab ncaj qha rau cov network uas siv IPv6 nkaus xwb yog tsis siv ib txoj kev hloov xws li NAT64.

Tsis tsim nyog ntsuas hosting tsuas yog raws li lus tshaj tawm “txhawb IPv6”. Nug kom meej: IPv6 puas raug route tawm mus rau Internet, puas siv tau rau lub npe sau npe tseem ceeb, tus muab kev pabcuam puas txhawb reverse DNS, firewall puas muaj kev tswj cais rau IPv6 thiab cov backup, kev saib xyuas puas paub txheeb xyuas IPv6 lawm lossis tseem tsis tau.

Daim ntawv txheeb xyuas kev teeb tsa IPv6 rau lub vev xaib

1. Paub meej chaw nyob IPv6 thiab kev pabcuam network

Ua ntej, muab chaw nyob IPv6 los ntawm nplooj tswj hosting lossis operating system. Ntawm Linux, koj tuaj yeem khiav:

ip -6 address
ip -6 route
ping6 -c 4 2001:4860:4860::8888

Qhov tshwm sim yuav tsum qhia tias network card muaj chaw nyob thoob ntiaj teb, muaj txoj kev IPv6 mặc định thiab muaj peev xwm tawm mus rau Internet. Chaw nyob uas pib nrog fe80:: tsuas yog link-local xwb, tsis tsim nyog siv los tshaj tawm lub vev xaib. Tsis txhob siv chaw nyob piv txwv uas nyob hauv pab chaw nyob rau ntaub ntawv 2001:db8::/32 hauv ib puag ncig tiag.

2. Teeb web server kom mloog IPv6

Nrog Nginx, kev teeb tsa feem ntau zoo li no:

server {
    listen 80;
    listen [::]:80;
    server_name example.com www.example.com;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name example.com www.example.com;
}

Apache tej zaum yuav tsum qhib kev mloog ntawm IPv6 chaw nyob uas phim. Tom qab hloov, kuaj bằng ss -lntp lossis siv cuab yeej tswj server. Yog pom tsuas yog 0.0.0.0:443 tabsis tsis muaj [::]:443, HTTPS IPv6 tej zaum tseem tsis tau ua haujlwm.

3. Qhib firewall IPv6 raws li lub hom phiaj

Tso cai rau TCP 80 thiab 443 ntawm IPv6 yog lub vev xaib xav tau HTTP thiab HTTPS. Tsis txhob qhib txhua lub chaw nres tsuas yog “kuaj kom sai”. Cov chaw nres tswj xws li SSH yuav tsum txwv raws li pab IP tswj, qhib kev txheeb xyuas thiab sau log. Kuaj tus muab kev pabcuam firewall, firewall hauv server thiab security group yog siv cloud server.

Yog lub vev xaib khiav WordPress, tsim nyog kuaj cov kev hloov hauv staging ib puag ncig ua ntej. Koj tuaj yeem saib txheej txheem kuaj WordPress plugin ua ntej hloov kho kom txo kev pheej hmoo thaum hloov server thiab plugin cov kev teeb tsa.

Kuaj DNS AAAA record, CDN thiab HTTPS

Kuaj DNS AAAA record

DNS AAAA record txuas lub npe sau rau qhov chaw nyob IPv6, zoo ib yam li A record txuas lub npe sau rau IPv4 (raws li Cloudflare Learning Center). Tshawb xyuas los ntawm kab lus txib:

dig AAAA example.com +short
dig AAAA www.example.com +short
dig A example.com +short

AAAA yuav tsum xa rov qab qhov chaw nyob uas lub server tab tom siv. Yog siv CDN, qhov tshwm sim yuav yog CDN qhov chaw nyob IPv6, tsis yog origin; qhov no tsis tas yuav yog qhov yuam kev. Thaum tsim lossis kho record, nco ntsoov tias TTL cuam tshuam rau lub sijhawm uas cov DNS resolver siv record tshiab (raws li Cloudflare DNS Docs).

Tsis txhob tsim AAAA rau lub npe sau tseem ceeb xwb ces tsis quav ntsej www, lub npe sau API, duab, ntaub ntawv rub tawm lossis subdomain uas siv hauv daim ntawv thov. Tsis tas li ntawd, tsis txhob taw AAAA mus rau server uas tseem tsis tau qhib chaw nres nkoj 443: ib pawg neeg siv yuav sim txuas los ntawm IPv6 tab sis tau txais qhov yuam kev timeout.

Tshawb xyuas CDN thiab txoj kev mus rau origin

CDN coob lub tuaj yeem txais kev nkag los ntawm IPv6 ntawm cov neeg siv txawm tias origin tsuas muaj IPv4 xwb. Piv txwv, Cloudflare hais tias hom IPv6 compatibility yuav tsim AAAA rau cov record uas tau proxy cia li; yog origin muaj IPv4 thiab IPv6 tib si, CDN yuav xaiv IPv4 ua ntej thaum txuas rov mus rau origin (raws li Cloudflare Network Docs).

Yog li, yuav tsum cais ob qho kev kuaj no:

• Client mus rau CDN: nug AAAA thiab txheeb xyuas tias browser txuas tau los ntawm IPv6.
• CDN mus rau origin: kuaj seb origin puas tso cai rau CDN IP range, TLS puas yog lub npe sau raug thiab firewall puas tsis thaiv IPv6.

Yog xav kuaj origin ncaj qha, siv hostname cais lossis DNS-only record ib ntus rau lub sijhawm luv, tab sis tsis tsim nyog cia origin qhov chaw nyob raug nthuav tawm ntev dua li qhov tsim nyog. Tom qab kuaj tas, rov qab kho proxy configuration thiab tshuaj xyuas cache.

Tshawb xyuas HTTPS, redirect thiab mixed content

Sim khiav:

curl -6 -I https://example.com
curl -6 -sS https://example.com -o /dev/null -w '%{http_code}n'

Qhov txiaj ntsig zoo feem ntau yog HTTP code raug cai xws li 200, 301 lossis 302 raws li tau teeb tsa. Kuaj seb TLS daim ntawv pov thawj puas npog lub npe sau raug, redirect puas tsis rov ua voj voog thiab CSS, JavaScript, font, duab cov peev txheej puas tsis taw mus rau hostname uas tsuas muaj IPv4 lossis HTTP URL uas ua rau mixed content.

Tshawb xyuas seb lub website puas txhawb IPv6 thiab daws teeb meem

Txheej txheem kuaj tiag tiag

1. Kuaj A thiab AAAA nrog tsawg kawg ob lub DNS resolver sib txawv.
2. Siv lub tshuab uas muaj kev txuas IPv6 tiag tiag, tsis txhob vam khom DNS qhov txiaj ntsig xwb.
3. Khiav curl -6 mus rau nplooj ntawv tseem ceeb, nplooj nkag mus, API thiab cov ntaub ntawv static tseem ceeb.
4. Qhib Developer Tools kom pom tias request twg ua tsis tiav lossis raug hloov mus rau hostname uas tsis muaj IPv6.
5. Kuaj web server, CDN, WAF thiab daim ntawv thov cov log nyob rau tib lub sijhawm.
6. Rov ntsuas dua tom qab TTL qub tas thiab kuaj cov npe sau theem qis thiab.

Cov cuab yeej kuaj IPv6 hauv online tuaj yeem pab txheeb xyuas dual-stack lub peev xwm, tab sis qhov txiaj ntsig tsuas qhia txog qhov chaw thiab lub sijhawm ntsuas ntawd xwb. Lub website uas muaj AAAA tsis tau txhais tias twb muab kev pabcuam tiav lawm yog tias firewall, TLS lossis daim ntawv thov sab nraud tseem muaj teeb meem. Yog li, kev kuaj HTTP txuas tiag tiag tseem yog theem txiav txim siab.

Teeb meem uas nquag ntsib thiab txoj kev kho

• DNS muaj AAAA tab sis timeout: kuaj route, IPv6 firewall thiab seb web server puas listen ntawm [::] lossis tseem tsis tau.
• Nplooj ntawv tseem ceeb khiav tab sis API muaj teeb meem: ntxiv AAAA, firewall thiab daim ntawv pov thawj rau API hostname; kuaj IP whitelist.
• CDN ua haujlwm tab sis origin muaj teeb meem: txheeb xyuas proxy hom, origin daim ntawv pov thawj thiab CDN qhov chaw nyob ntau yam uas tau tso cai nkag.
• Log sau IP tsis yog hom ntawv: hloov kho database kem, regex, spam tiv thaiv system thiab source code uas ua cov chaw nyob 128-bit.
• Qee tus neeg siv pom tias qeeb: kuaj IPv6 routing zoo li cas ntawm tus neeg muab network; khaws IPv4 nrog rau hauv tus qauv dual-stack es tsis txhob yuam kom siv IPv6-only.

Rau WordPress, kuaj ntxiv cov plugin ruaj ntseg, CAPTCHA, login txwv system, webhook thiab email xa kev pabcuam. Cov khoom no feem ntau muaj whitelist lossis logic cais rau kev ua cov IP chaw nyob. Yog xav tau txheej txheem tshuaj xyuas website hauv browser, saib tau txoj kev tswj thiab kuaj website hauv browser.

Xaus: yuav suav tau tias lub website npaj txhij rau IPv6 thaum DNS xa rov qab AAAA raug, server txais tau IPv6 kev txuas ntawm cov chaw nres nkoj tsim nyog, HTTPS thiab tag nrho cov peev txheej thauj khoom tau zoo, CDN/WAF sau tus neeg tuaj xyuas qhov chaw nyob raug thiab daim ntawv thov nrog cov kev saib xyuas system ua tau haujlwm nrog IPv6. Siv ib kauj ruam zuj zus, khaws IPv4 khiav ua ke, sau tseg configuration ua ntej hloov pauv thiab npaj txoj kev tshem AAAA sai yog pom muaj teeb meem thoob plaws.
