Class C IP Address Checker

The Class C IP Address Checker helps you quickly analyze any IPv4 address and identify its Class C network range, subnet block, and grouping. Whether you're performing an SEO audit, checking hosting networks, or verifying IP diversification, this tool gives fast and accurate results within seconds.

What Is a Class C IP Address?

A Class C IP address is an IPv4 address that ranges from 192.0.0.0 to 223.255.255.255.
It is commonly used for:

• Shared hosting environments
• Business networks
• SEO backlink analysis
• Private networks with up to 254 hosts

Class C networks provide 256 IPs, with 254 usable IP addresses for devices.

Why Use a Class C IP Address Checker?

This tool helps you:

• Identify whether two or more websites share the same Class C network
• Check IP diversification for SEO and backlink audits
• Avoid hosting multiple important websites on the same network block
• Analyze hosting infrastructure and server clustering
• Detect PBN footprints or unnatural backlink patterns

If two sites are in the same Class C range, search engines may treat them as related — important for SEO.

How the Tool Works

Simply enter any IPv4 address (e.g., 192.168.1.45) and the tool will show:

• Class C Network (192.168.1.xxx)
• Subnet Mask
• Network Address
• Broadcast Address
• Usable Host Range
• Total Number of Available Hosts

Everything is calculated instantly with accurate IPv4 addressing rules.

Understanding Class C IP Network Structure

A typical Class C IP address looks like:

192.168.1.24

Where:

192.168.1 = Network portion

.24 = Host portion

Class C networks use a default subnet mask of:

255.255.255.0

Which gives:

Network Address: 192.168.1.0

Broadcast Address: 192.168.1.255

Usable IP Range: 192.168.1.1 – 192.168.1.254
