IP Calculator
IP Calculator is a network planning tool that helps you understand and work with IP addresses and subnets. It calculates network ranges, subnet masks, usable addresses, and provides tools for network design and troubleshooting.
What it calculates:
- • Network address and broadcast address
- • Subnet mask and wildcard mask
- • Number of usable host addresses
- • First and last usable IP addresses
- • Subnet and supernet calculations
- • Reverse DNS (PTR) record information
Common uses:
- • Plan network subnets and IP allocation
- • Configure routers and firewalls
- • Troubleshoot network connectivity issues
- • Generate DNS zone files and PTR records
- • Understand network addressing schemes
How it works: Uses CIDR notation (Classless Inter-Domain Routing) to calculate network properties. CIDR allows flexible subnetting by specifying the number of network bits, enabling efficient IP address allocation and routing.
