AI IP Subnet Calculator

Intelligently calculate IP subnet division, supporting IPv4/IPv6, automatically calculate network address, broadcast address, available hosts, essential tool for network engineers

Subnet Calculator Interface

Interactive calculator will be available soon

Features

  • ✓ Supports IPv4 and IPv6 subnet calculation
  • ✓ Automatically calculate network address, broadcast address, available IP range
  • ✓ Supports CIDR notation and subnet mask conversion
  • ✓ Visual subnet division, intuitively display IP allocation
  • ✓ Batch calculate multiple subnets, generate network planning reports

How to Use

  1. Input IP address and subnet mask (or CIDR)
  2. Select IP version (IPv4/IPv6)
  3. Click calculate to view detailed network information
  4. Adjust subnet size, preview division results in real-time

FAQ

What is a subnet mask?

Subnet mask is used to distinguish network and host portions of an IP address. For example, 255.255.255.0 means first 24 bits are network address, last 8 bits are host address.

What is CIDR?

CIDR (Classless Inter-Domain Routing) is an IP address representation method, format is IP/prefix length. For example, 192.168.1.0/24 means first 24 bits are network address.

How to calculate available hosts?

Available hosts = 2^(32-prefix length) - 2. Minus 2 because network address and broadcast address cannot be assigned to hosts. For example, /24 subnet has 254 available hosts.

Does it support VLSM?

Yes. Can perform Variable Length Subnet Mask (VLSM) calculation, flexibly divide subnets of different sizes, optimize IP address usage.

Can I export calculation results?

Yes. Can export to CSV, PDF formats, including complete network planning information, convenient for documentation and team sharing.
