Game da Na'urar lissafin CIDR
Na'urar lissafin CIDR don IPv4 da IPv6: kewayon hanyar sadarwa, subnet mask, wildcard mask, adadin host, da juya adireshin farko da na ƙarshe zuwa rukunin CIDR.
Ɓangare ne na sashen “Bayanai da hanyar sadarwa” na SmartCalcy. Yana aiki a burauzar ku ba tare da asusu ba, yana amfani da kuɗinku da ma'aunanku (canza su a saman shafin), kuma yana ba da ƙiyasi don bayani kawai, don haka duba jagorar hukuma kafin ku dogara da sakamako.

Abin da yake lissafawa da lokacin amfani da shi
Yana lissafin kewayo, subnet mask, wildcard mask da girman CIDR block na IPv4 ko IPv6, yana karɓar adireshi tare da mask mai ɗigo, kuma yana juya adireshin farko da na ƙarshe zuwa mafi ƙanƙantar jerin CIDR blocks da ke rufe su daidai.
Yadda ake amfani da shi, mataki-mataki
- Zaɓi “CIDR block” ko “Kewayon adireshi”.
- Shigar da block kamar 192.168.10.0/22, ko adireshin farko da na ƙarshe na kewayo.
- Karanta adireshin farko da na ƙarshe, masks da adadin hosts.
- Don kewayo, kwafi jerin CIDR blocks.
Ma'anar kowace shigarwa
- CIDR Rukuni, ko address with mask – An IPv4 or IPv6 address followed by /prefix, or an IPv4 address and a dotted mask such as 255.255.252.0.
- Na farko da na ƙarshe address – The two ends of a range, both IPv4 or both IPv6.
Yadda ake karanta sakamako
- Address kewayo – The first and last address of the block, and the number of addresses.
- Masks – Subnet mask da wildcard mask akan IPv4.
- Usable hosts – Addresses available for devices: the total minus the network and broadcast addresses, except /31 and /32.
- CIDR Block – For a kewayo, the Mafi ƙaranci set na Block that covers it.
Dabarar lissafi
A /n block has 2^(bits − n) addresses, where bits is 32 for IPv4 and 128 for IPv6. The network address is the given address with the host bits set to zero. For IPv4 the usable hosts are 2^(32 − n) − 2. IPv6 uses BigInt arithmetic for exact results.
Misali da aka warware
192.168.10.0/22 covers 192.168.8.0 zuwa 192.168.11.255, which shi ne 1,024 addresses da 1,022 usable hosts, with mask 255.255.252.0.
Zato da iyakoki
- Usable hosts follow the usual convention of removing the network and broadcast addresses. /31 links use both addresses and /32 is a single host.
- IPv6 Block have no broadcast address.
- A range that does not fit one block returns several blocks.
Kurakuran da aka saba yi
- Entering a host address and expecting it to be the network address. The tool shows the real network address.
- Using a non-contiguous mask such as 255.0.255.0, which is not valid.
- Mixing an IPv4 first address with an IPv6 last address.
