Subnet Calculator (IPv4 CIDR)
Full IPv4 subnet kala qaybinta: network, broadcast, mask, wildcard, host range iyo tirada.
Natiijooyinka cusbooneysiinta sida aad ku qorto.
Ku saabsan Kalkaaliyahan
subnet calculator is a simple, easy-to-use tool that can be used to calculate the size of a subnet. The calculator uses the following metrics: IPv4 address, IPv6 address, IPv4 address, IPv6 address, IPv4 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6 address, IPv6
Su'aalaha badanaa la isweydiiyo
Sidee badan oo martida ah ayaa ku jira subnet?
A / n subnet leedahay 2 ^ (32−n) cinwaanka, ka yar laba ka reeban ee network iyo warbaahinta. A / 24 waxaa 256 cinwaanka iyo 254 martida isticmaali karo.
Waa maxay maskaxda wildcard?
A maskax wildcard waa bitwise ka soo horjeeda maskaxda subnet (255.0 → 0.255). Access-control liiska iyo OSPF isticmaalka si ay u wadaagaan kala duwanaansho ah oo ah cinwaanka.
Waa maxay farqiga u dhexeeya network iyo cinwaanka broadcast?
Xarunta network (hosts dhammaan bits 0) magacyada subnet; xarunta broadcast (hosts dhammaan bits 1) gaadhay hosts oo dhan on it. Labada midkoodna ma aha in la siiyo qalab.
Maxaa ka horjeeda CIDR (/24, /16) ka dhigan?
Waa tirada biita hogaaminaya oo ka kooban qaybta network ee cinwaanka. A weyn oo hore u macnaheedu yahay biita network badan iyo biita host yar, sidaas subnet yar: / 24 siiyaa 254 martida, / 25 siiyaa 126, iyo biita dheeraad ah oo dhan hal mar block.
Sideen u kala qaybiyaa shabakad subnets yar yar?
Biisha martida la siiyo by kordhinta hore. kala qaybinta /24 laba /25s siiyaa laba blocks of 126 martida; /26 u socdaa si ay siiyaan afar blocks of 62. kasta oo ku daray hore bit laba jeer tirada subnets iyo halbeegga ay miisaanka.
Maxaa ah IP cinwaanka fasalka?
Qorshaha classful hore qaybsan cinwaanka by octet-kooda koowaad: Class A (1-126), Class B (128-191) iyo Class C (192-223) ee unicast, iyo D ee multicast iyo E la ilaaliyo. CIDR badalay fasalada loogu talagalay qaybinta, laakiin xisaabinta weli warbixinno fasalka cinwaanka ku dhaca.
Maxay yihiin / 31 iyo / 32 subnets loo isticmaalo?
A / 31 waxaa kaliya laba cinwaanno iyo waxba ma baahinta, loo isticmaalo xiriirada point-to-point u dhexeeya routers. A / 32 waa cinwaan host kaliya, caadiga ah loo yaqaan loopabacks iyo jidka martida. Kalkaaliyayaasha labadaba maxkamadaha gaar ah.
