CIDR Calculator: Turant Subnet & IP Ranges

CIDR calculator jo kisi bhi IPv4 block ke liye network, broadcast, netmask, wildcard aur host range nikaalta hai, sab kuch locally process hota hai taaki data device par hi rahe.

Aapka CIDR input aapke browser mein locally process hota hai aur kuch bhi server par upload nahi hota.

CIDR / Subnet Calculator ke baare mein

Yeh cidr calculator 192.168.1.0/24 jaise kisi IPv4 CIDR block ko poore subnet breakdown mein badal deta hai: network address, broadcast address, netmask, wildcard mask, pehla aur aakhri usable host, prefix length, aur total aur usable host counts. Ek subnet calculator ki tarah yeh network engineers, sysadmins, DevOps aur developers ko IP ranges plan karne, VPC aur VLAN subnets size karne, firewall aur routing rules likhne, aur ACLs ko binary math haath se kiye bina double-check karne mein madad karta hai. Bas ek block type karein aur results turant update ho jaate hain. Yeh /31 point-to-point links aur /32 host routes jaise edge cases ko sahi se handle karta hai, jahaan minus-two host rule laagu nahi hota. Sab kuch aapke browser mein locally process hota hai, isliye aapki network details aur aapka data kabhi aapke device se bahar nahi jaata.

Features

  • Kisi bhi IPv4 CIDR block (0-32 prefix) ko poore subnet report mein parse karta hai
  • Block ke network aur broadcast addresses dikhaata hai
  • Prefix length se netmask aur wildcard mask nikaalta hai
  • Range mein pehla aur aakhri usable host address list karta hai
  • Total host count aur usable host count report karta hai
  • /31 aur /32 edge cases ko handle karta hai jahaan host range alag hoti hai
  • Block ke kisi bhi address ko apne-aap network base par normalise karta hai
  • Type karte hi results live update karta hai, saaf validation messages ke saath

CIDR / Subnet Calculator kaise use karein

  1. CIDR block field mein 192.168.1.0/24 jaisa koi CIDR block type ya paste karein.
  2. Results grid se network, broadcast, netmask aur wildcard values padhein.
  3. First host, last host, total hosts aur usable hosts check karein taaki range aapki zaroorat ke hisaab se fit ho.
  4. Prefix length adjust karein taaki dekh sakein ki alag subnet sizes host count ko kaise badalti hain.

Example

Input

192.168.1.0/24

Output

Network:      192.168.1.0
Broadcast:    192.168.1.255
Netmask:      255.255.255.0
Wildcard:     0.0.0.255
First host:   192.168.1.1
Last host:    192.168.1.254
Prefix:       /24
Total hosts:  256
Usable hosts: 254

Ek /24 block apni poori subnet details mein expand hua.

Common errors aur troubleshooting

  • Prefix ke bina address daalna, jaise 192.168.1.0. — Slash aur prefix length add karein, jaise 192.168.1.0/24, taaki calculator ko subnet size pata chale.
  • 255 se upar wala octet use karna, jaise 192.168.300.0/24. — Chaaron octets 0 aur 255 ke beech hone chahiye; out-of-range octet theek karein aur block dobara enter karein.
  • /31 ya /32 par usable hosts ko total minus two maan lena. — /31 (point-to-point) aur /32 (single host) blocks mein dono addresses usable hote hain, isliye tool network aur broadcast addresses minus nahi karta.
  • IPv4 ke liye 32 se bada prefix type karna. — IPv4 prefix lengths 0 se 32 tak hoti hain; usi range ki value use karein. IPv6 blocks supported nahi hain.
  • 192.168.1.42/24 jaisa host address daalkar use waise hi wapas milne ki ummeed karna. — CIDR calculator input ko network base par normalise karta hai, isliye 192.168.1.42/24 network ko 192.168.1.0 report karta hai.

Aksar pooche jaane wale sawaal

CIDR calculator kya hai aur kya dikhaata hai?
Ek CIDR calculator IPv4 block ko network aur broadcast addresses, netmask, wildcard mask, pehle aur aakhri usable host, prefix length, aur total aur usable host counts dono mein expand karta hai.
CIDR prefix ko subnet mask mein kaise convert karein?
CIDR calculator mein 10.0.0.0/20 jaisa block enter karein aur yeh matching netmask (255.255.240.0) aur uske saath wildcard mask dikhaata hai.
Subnet ke liye usable hosts kaise calculate hote hain?
Zyada blocks ke liye usable hosts = total addresses minus network aur broadcast addresses. /31 aur /32 blocks ke liye CIDR calculator har address ko usable ginta hai.
Kya yeh CIDR calculator IPv6 subnets support karta hai?
Nahi, yeh tool 0 se 32 prefixes wale IPv4 CIDR blocks handle karta hai. IPv6 kaam ke liye, addresses ko IPv6 to IPv4 Converter se convert karein.
Kya CIDR calculator mein meri IP aur network data private rehti hai?
Haan. CIDR calculator poori tarah aapke browser mein chalta hai, kuch bhi server par upload nahi hota, aur aapki network details kabhi aapke device se bahar nahi jaati.
