Carane nganggo Kalkulator CIDR
Apa sing dietung lan kapan nganggo
Ngetung rentang, subnet mask, wildcard mask lan ukuran blok CIDR kanggo IPv4 utawa IPv6, nampa alamat kanthi mask titik, lan ngowahi alamat wiwitan lan pungkasan dadi daftar blok CIDR paling cilik sing nutupi persis.
Carane nganggo, langkah demi langkah
- Pilih “Blok CIDR” utawa “Rentang alamat”.
- Lebokna blok kayata 192.168.10.0/22, utawa alamat pisanan lan pungkasan saka sawijining rentang.
- Waca alamat pisanan lan pungkasan, mask lan cacahe host.
- Kanggo rentang, salin daftar blok CIDR.
Tegese saben input
- CIDR Blok, utawa 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.
- Ngarep lan mburi address – The two ends of a range, both IPv4 or both IPv6.
Carane maca asile
- Address jangkauan – The first and last address of the block, and the number of addresses.
- Masks – Subnet mask lan wildcard mask kanggo IPv4.
- Usable hosts – Addresses available for devices: the total minus the network and broadcast addresses, except /31 and /32.
- CIDR Blok – For a jangkauan, the Minimal set Blok that covers it.
Rumus
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.
Conto petungan
192.168.10.0/22 covers 192.168.8.0 nganti 192.168.11.255, which yaiku 1,024 addresses lan 1,022 usable hosts, with mask 255.255.252.0.
Asumsi lan watesan
- 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 Blok have no broadcast address.
- A range that does not fit one block returns several blocks.
Kesalahan umum
- 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.
Pitakonan sing kerep ditakokake
Apa iku notasi CIDR?
Cara nulis rentang alamat minangka alamat lan dawa prefix, kayata 10.0.0.0/8, ing ngendi prefix iku cacahe bit ngarep sing tetep.
Pira host ing /24?
256 alamat lan 254 host sing bisa digunakake.
Apa iku wildcard mask?
Kebalikane subnet mask, digunakake ing access list. Kanggo 255.255.255.0 yaiku 0.0.0.255.
Apa iku /64 ing IPv6?
Ukuran standar siji subnet IPv6, kanthi 2^64 alamat.
Apa sawijining rentang mesthi bisa dadi siji blok?
Mung yen diwiwiti ing wates lan ukurane pangkat loro. Yen ora, dipecah dadi pirang-pirang blok.
