Uyazi ukuthi yini i-IPv6?

I-IPv6 isifinyezo se-"Internet Protocol Version 6".

• I-IPv6 isizukulwane esilandelayo somthetho olandelwayo we-inthanethi, esingena esikhundleni sephrothokholi yamanje ye-IP, inguqulo 4 ye-IP.
• I-IPv6 inguqulo elandelayo Yephrothokholi Ye-inthanethi, kungashiwo ukuthi isizukulwane esilandelayo seProtokholi ye-inthanethi.
• Kwahlongozwa ekuqaleni ngoba ngokuthuthukiswa okusheshayo kwe-inthanethi, incazelo yesikhala esilinganiselwe samakheli e-IPv4 izophela, futhi ukuntuleka kwesikhala samakheli kuzokhinyabeza ukuthuthuka okuqhubekayo kwe-inthanethi.

Ukuze kwandiswe isikhala sekheli, kuhlongozwa ukuthi kuchazwe kabusha isikhala sekheli nge-IPv6, futhi i-IPv6 isebenzisa ubude bekheli obuyi-128-bit cisheokungenamkhawulonikeza ikheli.

Ngokwezilinganiso eziqinile zamakheli angempela e-IPv6 anganikezwa, amakheli angaphezu kuka-1,000 asenganikezwa imitha yesikwele ngayinye yomhlaba.

Ngaphezu kokubhekana nokushoda kwamakheli unomphela phakathi nenqubo yokuklama i-IPv6, ezinye izinkinga ezingasingathwanga kahle ku-IPv4 zicatshangelwe:

1. Ihlanganisa ikakhulukazi ukuxhumana kwe-IP kokuphela kuya ekupheleni,
2. Ikhwalithi Yesevisi (QoS),
3. ukuphepha,
4. nokunye ukusakaza okuningi,
5. nyakaza,
6. Xhuma futhi udlale njll.

I-IPv6 inalezi zici kanye nezinzuzo?

• Uma kuqhathaniswa ne-IPv6, yiziphi izici nezinzuzo?

1) Indawo yekheli enkudlwana.

• IPv4指定的IP地址长度为32，即2 ^ 32-1地址？
• 但是，如果IPv6的IP地址的长度为128，则有2 ^ 128-1个地址。

2) Itafula elincane lomzila.

• Ukunikezwa kwekheli le-IPv6 kulandela umgomo wokuhlanganisa (ukuhlanganiswa) kusukela ekuqaleni, okwenza amarutha abe namarekhodi (okokufaka) kumathebula omzila ukuze amele amanethi angaphansi.
• Lokhu kunciphisa kakhulu ubude be-router etafuleni lomzila futhi kwandisa isivinini lapho umzila ungadlulisela khona amaphakethe.

3) Ukusekelwa kwe-multicast okuthuthukisiwe (i-Multicast) nokusekelwa kwe-convection (Ukulawula ukugeleza).

• Lokhu kwenza izinhlelo zokusebenza zemultimedia kunethiwekhi zibe namathuba amakhulu okuthuthukisa,
• Futhi inikeza inkundla yenethiwekhi enhle yokulawula ikhwalithi yesevisi (QoS).
• Ukwesekwa okungeziwe kokucushwa okuzenzakalelayo (ukumisa okuzenzakalelayo).

Lokhu ukuthuthukiswa nokunwetshwa kwephrothokholi ye-DHCP, okwenza ukuphathwa kwenethiwekhi (ikakhulukazi inethiwekhi yendawo yendawo) kube lula, kusheshe futhi kuphephe.

Kumanethiwekhi asekela i-IPv6, abasebenzisi bangabhala ngemfihlo idatha futhi bahlole amaphakethe e-IP kusendlalelo senethiwekhi, okuthuthukisa kakhulu ukuphepha kwenethiwekhi.

Uyimisa kanjani i-Vultr ukuze inike amandla i-IPv6?

Ukumisa ikheli le-IPv6 le-Vultr VPS kulula kakhulu. Okulandelayo inqubo yokumisa:

isinyathelo 1:Bhalisela i-akhawunti ye-Vultr VPS mahhala (thola ikhodi yesaphulelo engu-$10) ▼

Isinyathelo sesi-2:Thenga i-VPS, hlola okuthi "Vumela i-IPv6" kuphaneli ▼

• Lungiselela inethiwekhi yekheli le-IPv6 kungemuva le-Vultr VPS ▼

Isinyathelo sesi-3:Kuphaneli ye-backend ye-Vultr, chofoza Qala kabusha i-VPS ukuze izinguquko zisebenze ▼

isinyathelo 4:Ixazulula amakheli e-IPv6

• Kunconywa ukuthi usebenzise i-DNSPod ukuze uxazulule igama lesizinda sakho. Kuphaneli yangemuva ye-DNSPod, engeza amarekhodi e-AAAA futhi uxazulule amakheli e-IPv6.

Isinyathelo sesi-5:ukuhlolwa kwe-ping ikheli le-IPv6

• Ngaphansi kwezimo ezijwayelekile, ngemva kokuqeda izinyathelo ezingenhla, ungakwazi ukuhlola ikheli lakho le-IPv6.
• Kunconywa ukusebenzisa amathuluzi alandelayo okuhlola i-ping ▼

Ikheli le-IPv6 lokucushwa kwe-VPS

Uma uhlangabezana nezinkinga, ungangeza izilungiselelo ze-IPv6 kuye ngenguqulo yesistimu ye-VPS.

Ukuze uthole imininingwane, sicela uvakashele imibhalo esemthethweni yakwa-Vultr bese wengeza ngokwakho ikheli le-IPv6 ▼

CentOSuhlelo

KW /etc/sysconfig/network-scripts/ifcfg-eth0 Engeza imigqa elandelayo ku:

(Sicela ufake ikheli lakho le-VPS IPv6 esikhundleni sekheli elibomvu elingenhla)

Isibonelo Sokucushwa Kwenethiwekhi Yekheli le-IPv6

Ukuze uthole ireferensi yakho, ifayela lokucushwa kwenethiwekhi elilungile le-VPS yamanje liyaboniswa.

Ngaphambi kokuvula isixhumanisi esingezansi, sicela uguqule ikhodi ekugcineni kwe-URL engezansi ibe inombolo yakho ye-VPS ▼

I-Vultr ilungiselela kanjani ukukhubaza amakheli e-IPv6?

Lapho uqalisa kabusha, khubaza i-IPv6 unomphela:

Uma ufuna ukuvala i-IPv6, indlela elandelayo ingakwenza.

Vula ifayela ngomhleli wombhalo▼

/etc/sysctl.conf

Engeza okulandelayo ▼

＃在系统范围内的所有接口上禁用IPv6
net.ipv6.conf.all.disable_ipv6 = 1

＃在特定接口上禁用IPv6（例如，eth0，lo）
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1

Ukuze wenze lezi zinguquko zisebenze ku-/etc/sysctl.conf, sebenzisa:

$ sudo sysctl -p /etc/sysctl.conf

Noma vele uqale kabusha i-VPS.
