Cara menggunakan CIDR calculator
Apa yang dihitung dan kapan digunakan
Works out the Rentang, subnet mask, wildcard mask, dan size a CIDR block seharga IPv4 atau IPv6, accepts an address with a dotted mask,, dan converts a start dan end address into the smallest list CIDR blocks that cover them exactly.
Cara menggunakan, langkah demi langkah
- Choose “CIDR block” atau “Address Rentang”.
- Enter a block such as 192.168.10.0/22, or the first, dan last address a range.
- Read the first dan last address, masks, dan number hosts.
- For a Rentang, Salin the list CIDR blok.
Arti setiap input
- CIDR block, atau address with mask – An IPv4 atau IPv6 address followed by /prefix, or an IPv4 address, dan a dotted mask such as 255.255.252.0.
- First dan last address – The two ends a range, both IPv4 atau both IPv6.
Cara membaca hasil
- Address Rentang – The first dan last address the block, dan the number addresses.
- Masks – Subnet mask dan wildcard mask seharga IPv4.
- Usable hosts – Addresses available seharga devices: the total minus the network dan broadcast addresses, except /31, dan /32.
- CIDR blok – For a Rentang, the minimum set blok that covers it.
Rumus
A /n block has 2^(bit − n) addresses, where bits adalah 32 seharga IPv4, dan 128 seharga IPv6. The network address adalah the given address with the host bits set to zero. For IPv4 the usable hosts are 2^(32 − n) − 2. IPv6 uses BigInt arithmetic seharga exact results.
Contoh perhitungan
192.168.10.0/22 covers 192.168.8.0 sampai 192.168.11.255, which adalah 1,024 addresses, dan 1,022 usable hosts, with mask 255.255.252.0.
Asumsi dan batasan
- Usable hosts follow the usual convention removing the network dan broadcast addresses. /31 links use both addresses dan /32 adalah a single host.
- IPv6 blok have Tidak broadcast address.
- A Rentang that does not Bugar one block returns several blok.
Kesalahan umum
- Entering a host address dan expecting it sampai be the network address. The tool shows the real network address.
- Using a non-contiguous mask such as 255.0.255.0, which adalah not valid.
- Mixing an IPv4 first address with an IPv6 last address.
Pertanyaan yang sering diajukan
What adalah CIDR notation?
A way writing an address range as an address dan a prefix length, such as 10.0.0.0/8, where the prefix adalah the number fixed leading bits.
How many hosts are di a /24?
256 addresses dan 254 host yang dapat dipakai.
What adalah a wildcard mask?
The inverse the subnet mask, used di access lists. For 255.255.255.0 it adalah 0.0.0.255.
What adalah a /64 di IPv6?
The standard Ukuran one IPv6 subnet, with 2^64 addresses.
Kaleng a Rentang always be one block?
Only if it starts on a boundary dan its size adalah a power two. Otherwise it adalah split into several blocks.
