IP Range Calculator
Calculate span and total quantity of addresses between start and end IPv4 addresses.
Total IP Addresses: 254
How It Works
- Parses IPs into 32-bit integers and calculates inclusive span delta.
Formula & Technical Standard
Address Count = (End IP as UInt32) - (Start IP as UInt32) + 1
Practical Example
Scope Span
Input: 10.0.0.1 to 10.0.0.254
Output: 254 addresses
Inclusive host count.
Frequently Asked Questions
