Cim hauv zos chaw nyob
0.0/8, 172.16. 0.0/12 thiab 192.168. 0.0/16). Lawv yog routable tsuas yog nyob rau hauv ib pawg ntawm kev koom tes.
Kuj kom paub yog, qhov chaw nyob IPv6 twg yog qhov chaw nyob?
IPv6 Unicast
- Ntiaj teb no unicast chaw nyob, uas yog cov pa, chaw nyob publiclyroutable, ib yam li cov pa IPv4 pej xeem routableaddresses.
- Txuas-qhov chaw nyob yog zoo li tus kheej, tsis yog-routableaddresses hauv IPv4 (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
Tsis tas li ntawd, muaj pes tsawg tus IPv6 chaw nyob tuaj yeem ua tau? IPv6 siv 128-ntsis chaw nyob uas tso cai rau 2128, los yog kwv yees li 3.4 x 1038 chaw nyob . 3.4x 1038 yog sib npaug rau 340 undecillionIP chaw nyob.
Ib sab saum toj no, IPv6 tus kheej chaw nyob yog dab tsi?
IPv6 chaw nyob Ib ipv6 npe siv 128 me ntsis as opposed to 32bits in IPv4. Vim tias tus lej hexadecimal siv 4 cov khoom no txhais tau tias ib qho IPv6 chaw nyob muaj 32 hexadecimalnumbers.
Qhov chaw nyob rfc1918 yog dab tsi?
Cov RFC1918 ntau yam yog: 10.0.0.0 - 10.255.255.255(10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12prefix)

Qhov txawv ntawm qhov chaw nyob thiab qhov chaw nyob yog dab tsi?
Qee zaum, 'txoj kev chaw nyob' hais txog koj lub cev qhov chaw nyob ntawm qib zoo dua hauv nroog. Piv txwv li, '1313Mockingbird Lane', tsis muaj lub nroog lub npe txuas nrog. Tab sis yog, feem ntau nws tsuas yog ib daim ntawv rov qab kom paub qhov txawv ntawm qhov chaw xa ntawv (thaum chiv keeb) thiab tam sim no e-mail chaw nyob, chaw nyob hauv web, IPaddress, thiab lwm yam
Qhov chaw nyob ntawm lub cev thiab qhov chaw nyob qhov chaw nyob yog dab tsi?
Qhov sib txawv yooj yim ntawm Logical thiab lub cev chaw nyob yog qhov chaw nyob Logical yog tsim los ntawm CPU hauv kev xav ntawm ib qho kev pab cuam. Ntawm qhov tod tes, qhov chaw nyob ntawm lub cev yog qhov chaw nyob uas muaj nyob hauv lub cim xeeb. Cov txheej txheem ntawm txhua qhov chaw nyob uas tsim los ntawm CPU fora program hu ua Logical Address Space
Muaj pes tsawg cov khoom nyob hauv txhua qhov chaw ntawm IPv6 chaw nyob?
Qhov chaw nyob IPv6 yog 128 me ntsis hauv qhov ntev thiab muaj yim, 16-ntsis teb, nrog rau txhua daim teb bounded los ntawm txoj hnyuv. Txhua daim teb yuav tsum muaj tus lej hexadecimal, sib piv rau dotted-decimal cim ntawm IPv4 chaw nyob. Hauv daim duab tom ntej, tus x yog tus lej hexadecimal
Dab tsi yog qhov chaw nyob thiab lub cev nyob hauv OS?
Qhov sib txawv yooj yim ntawm Logical thiab lub cev chaw nyob yog qhov chaw nyob Logical yog tsim los ntawm CPU hauv kev xav ntawm ib qho kev pab cuam. Ntawm qhov tod tes, qhov chaw nyob ntawm lub cev yog qhov chaw nyob uas muaj nyob hauv lub cim xeeb. Cov txheej txheem ntawm txhua qhov chaw nyob uas tsim los ntawm CPU rau ib qho kev pab cuam hu ua Logical Address Space
Qhov txawv ntawm qhov chaw nyob sib txuas lus thiab qhov chaw nyob ruaj khov yog dab tsi?
Qhov chaw nyob xa ntawv yog chaw nyob sib txuas lus piv txwv li qhov koj nyob tam sim no. & chaw nyob Apermanent yog ntawm koj cov ntaub ntawv yog sau rau ntawm koj daim ntawv pov thawj hnub yug & daim npav pov npav. Qhov chaw nyob ruaj khov & kev sau ntawv yuav zoo ib yam lossis txawv ntawm cov ntaub ntawv siv tau
