Paub dab tsi yog IPv6?

IPv6 yog lub ntsiab lus rau "Internet Protocol Version 6".

• IPv6 yog cov txheej txheem txuas ntxiv rau Is Taws Nem, hloov pauv tus IP raws tu qauv tam sim no, IP version 4.
• IPv6 yog qhov txuas ntxiv ntawm Internet Protocol, nws tuaj yeem hais tias yog Internet Protocol tiam tom ntej.
• Nws yog thawj zaug tau npaj tseg vim tias nrog kev txhim kho sai ntawm Is Taws Nem, lub ntsiab lus ntawm IPv4 qhov chaw nyob txwv yuav raug tso tseg, thiab qhov tsis muaj chaw nyob yuav cuam tshuam rau kev txhim kho ntxiv ntawm Is Taws Nem.

Txhawm rau nthuav dav qhov chaw nyob, nws tau thov kom rov hais dua qhov chaw nyob ntawm IPv6, thiab IPv6 siv 128-ntsis chaw nyob ntev mus yuav luag.txwvmuab qhov chaw nyob.

Raws li kev kwv yees kwv yees ntawm qhov tseeb IPv6 chaw nyob uas tuaj yeem faib tau, ntau dua 1,000 qhov chaw nyob tseem tuaj yeem faib rau ib square meter ntawm lub ntiaj teb.

Ntxiv rau qhov hais txog qhov chaw nyob tsis txaus ib zaug thiab rau tag nrho thaum lub sij hawm tsim IPv6 txheej txheem, lwm yam teeb meem uas tsis zoo nyob rau hauv IPv4 raug txiav txim siab:

1. Feem ntau suav nrog qhov kawg-rau-kawg IP kev sib txuas,
2. Quality of Service (QoS),
3. kev nyab xeeb,
4. thiab ntau yam tshaj tawm,
5. txav,
6. Plug thiab ua si thiab lwm yam.

IPv6 muaj cov yam ntxwv thiab qhov zoo?

• Piv nrog IPv6, cov yam ntxwv thiab qhov zoo yog dab tsi?

1) Qhov chaw nyob loj dua.

• 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) Lub rooj sib tham me me.

• IPv6 qhov chaw nyob ua raws li kev sib sau (aggregation) hauv paus ntsiab lus los ntawm qhov pib, uas ua rau routers muaj cov ntaub ntawv (inputs) nyob rau hauv routing tables los sawv cev subnets.
• Qhov no zoo heev txo qhov ntev ntawm lub router nyob rau hauv lub rooj routing thiab ua rau kom qhov ceev uas lub router tuaj yeem xa cov pob ntawv.

3) Txhim kho kev txhawb nqa multicast (Multicast) thiab kev txhawb nqa convection (Flow-control).

• Qhov no ua rau cov ntawv thov multimedia hauv lub network muaj txoj hauv kev loj hlob,
• Thiab nws muab lub platform zoo rau kev pabcuam zoo (QoS) tswj.
• Ntxiv kev txhawb nqa rau autoconfiguration (autoconfiguration).

Qhov no yog kev txhim kho thiab txuas ntxiv ntawm DHCP raws tu qauv, uas ua rau kev tswj hwm ntawm lub network (tshwj xeeb tshaj yog hauv cheeb tsam network) yooj yim dua, sai dua thiab nyab xeeb dua.

Hauv cov tes hauj lwm uas txhawb nqa IPv6, cov neeg siv tuaj yeem nkag siab cov ntaub ntawv thiab tshuaj xyuas cov pob ntawv IP ntawm txheej txheej network, uas ua rau muaj kev ruaj ntseg zoo heev.
