IPv4 thiab IPv6 yog ob versions ntawm Internet raws tu qauv (IP), thiab muaj qee qhov sib txawv tseem ceeb ntawm lawv.Nov yog qee qhov sib txawv tseem ceeb ntawm lawv:
1. Chaw nyob ntev:IPv4siv 32-ntsis chaw nyob ntev, uas txhais tau hais tias nws tuaj yeem muab txog 4.3 billion qhov chaw sib txawv.Hauv kev sib piv, IPv6 siv 128-ntsis chaw nyob ntev thiab tuaj yeem muab kwv yees li 3.4 x 10^38 chaw nyob, tus lej uas nyob deb tshaj qhov chaw nyob ntawm IPv4.
2. Txoj kev sawv cev chaw nyob:IPv4 chaw nyob feem ntau yog qhia hauv dotted decimal format, xws li 192.168.0.1.Hauv qhov sib piv, IPv6 chaw nyob siv cov lus cim hexadecimal, xws li 2001: 0db8: 85a3: 0000: 0000: 8a2e: 0370: 7334.
3. Routing thiab network tsim:Txij li thaumIPv6muaj qhov chaw nyob loj dua, txoj kev sib sau ua ke tuaj yeem ua tau yooj yim dua, uas pab txo qhov loj ntawm cov rooj sib tham thiab txhim kho routing efficiency.
4. Kev ruaj ntseg:IPv6 suav nrog kev txhawb nqa kev ruaj ntseg, suav nrog IPSec (IP Security), uas muaj peev xwm encryption thiab authentication.
5. Tsis siv neeg configuration:IPv6 txhawb kev teeb tsa tsis siv neeg, uas txhais tau hais tias lub network interface tuaj yeem tau txais qhov chaw nyob thiab lwm yam ntaub ntawv teeb tsa yam tsis muaj phau ntawv teeb tsa.
6. Hom kev pabcuam:IPv6 ua rau nws yooj yim dua los txhawb cov kev pabcuam tshwj xeeb, xws li kev siv xov xwm ntau thiab siv sijhawm.
7. Mobility:IPv6 tau tsim los nrog kev txhawb nqa rau cov khoom siv txawb hauv siab, ua kom yooj yim dua los siv IPv6 ntawm cov xov tooj ntawm tes.
8. Header format:Lub header hom ntawm IPv4 thiab IPv6 kuj txawv.Lub IPv4 header yog ib qho ruaj 20 bytes, thaum IPv6 header yog qhov sib txawv ntawm qhov loj.
9. Kev Pabcuam Zoo (QoS):IPv6 header muaj ib daim teb uas tso cai rau qhov tseem ceeb ntawm kev kos npe thiab kev faib tsheb, uas ua rau QoS yooj yim dua rau kev siv.
10. Multicast thiab tshaj tawm:Piv nrog IPv4, IPv6 zoo dua txhawb nqa multicast thiab tshaj tawm txoj haujlwm.
IPv6 muaj ntau yam zoo dua IPv4, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm qhov chaw nyob, kev ruaj ntseg, kev mus los thiab kev pab hom.Nyob rau hauv lub xyoo tom ntej, peb yuav pom ntau cov khoom siv thiab cov tes hauj lwm tsiv mus rau IPv6, tshwj xeeb yog tsav los ntawm IoT thiab 5G thev naus laus zis.
