I-Calculator ye-Subnet (IPv4 CIDR)
IPv4 i-subnet epheleleyo eqhutywa: uthungelwano, usasazo, imask, i-wildcard, ummandla womququzeleli kunye nobalo.

Imibuzo ebuza rhoqo
Ingaba zininzi iziququzeleli kwinethiwekhi esezantsi?
A /n umxhobho wesiqhagamshelanisi esingaphantsi une-2^(32−n) idilesi, ngaphantsi kwesibini ezigcinwe kuthungelwano nokusasazwa. A /24 une-256 idilesi ne-254 iindwendwe ezisetyenziswayo.
Yintoni isigqubuthelo se wildcard?
Isigqubuthelo se-wildcard siyi-bitwise ejikelezayo yesigqubuthelo somthungelwano phantsi (255.0 → 0.255). Uluhlu lokufikelela-ulawulo kunye ne-OSPF zisebenzisa ukuhambelana noluhlu lweedilesi.
Yintoni utshintsho phakathi kothungelwano kunye nedilesi yosasazo?
Idilesi yothungelwano (zonke iinkwenkwezi zomququzeleli 0) inika igama lothungelwano olusezantsi; idilesi yosasazo (zonke iinkwenkwezi zomququzeleli 1) ifika kumququzeleli ngamnye kuyo. Akukho nto inganikezelwa kwisixhobo.
Ithetha ntoni isiqalelo se-CIDR (/24, /16)?
Inani lezinto eziphambili ezidibanisa inxalenye yomsebenzi womnatha wedilesi. Isiqalelo esikhulu sithetha izinto ezingaphezulu zomsebenzi womnatha kunye nezinto ezincinci zomququzeleli, ngoko ke isixhobo esincinci somsebenzi womnatha: / 24 sinika 254 zomququzeleli, / 25 sinika 126, kwaye yonke into engaphezulu idibanisa inxalenye yesibini yebloki.
Ndiyahlula njani uthungelwano lube ziinethiwekhi ezincinci?
Iibit zenginginya ezimfutshane ngokunyusa isiqalelo. Ukwahlula / 24 kwi / 25s ezimbini kunika iibloki ezimbini ze 126 zeziqhagamshelanisi; ukuphuma kwi / 26 kunika iibloki ezine ze 62. Iibit zenginginya ezimfutshane ezifakiwe nganye ziphindaphindwe inani le subnets kwaye ziphelelwe lixesha ubungakanani babo.
Yintoni udidi lwedilesi ye-IP?
Inkqubo edala yohlobo olutsha ihlula idilesi nge octet yabo yokuqala: Uhlobo A (1-126), Uhlobo B (128-191) nohlobo C (192-223) ye-unicast, kunye ne-D ye-multicast ne-E egcinwe. I-CIDR itshintshe amaqela okunikezelwa, kodwa i-calculator ihlala ixela uhlobo idilesi iwela kulo.
Yintoni /31 ne /32 iinxuwa ezisezantsi ezisetyenziswa kuzo?
A / 31 ineedilesi ezimbini kuphela kwaye akukho kusasazo, isetyenziswa kwikhonkco lendawo- ukuya- kwindawo phakathi kwee routers. A / 32 idilesi yomququzeleli omnye, eqhelekileyo kwi loopbacks kunye neendlela zomququzeleli. I kalkuleta iphatha zombini iimeko ezikhethekileyo.
