Online IP Address & Subnet Inspector
Analyze IPv4 and IPv6 addresses, inspect network class and scope (Public, Private RFC1918, Loopback), calculate subnet CIDRs, and convert between binary, hex, and integer representations.
About This Tool
ToolSnippet's IP Address & Subnet Inspector is a network diagnostic utility for network administrators, cloud engineers, and software developers. It decomposes IP addresses, determines routing scopes, calculates subnet ranges, and displays multi-base representations.
Key Features
How to Use
- 1Type or paste an IPv4 address (e.g. 192.168.1.1 or 8.8.8.8) or IPv6 address into the input box.
- 2Or click 'Detect My Public IP' to inspect your active connection.
- 3Adjust the CIDR prefix slider (/1 to /32) to calculate subnet boundaries.
- 4Inspect the network breakdown: Network Address, Broadcast Address, Usable Host Range, and Total Hosts.
- 5View the binary, hexadecimal, and 32-bit integer representations of the IP.
Why Use ToolSnippet IP Address & Subnet Inspector?
Tips for Best Results
- Use /28 subnets for small database subnets (14 usable hosts) and /24 for standard application tiers (254 usable hosts).
- Remember that in AWS VPCs, 5 IP addresses per subnet are reserved by AWS.
Frequently Asked Questions
What are RFC 1918 private IP address ranges?
RFC 1918 designates three non-routable private IP blocks for local networks: 10.0.0.0/8 (10.0.0.0 – 10.255.255.255), 172.16.0.0/12 (172.16.0.0 – 172.31.255.255), and 192.168.0.0/16 (192.168.0.0 – 192.168.255.255).
How do I calculate usable hosts in a /24 subnet?
A /24 subnet has 8 host bits (2^8 = 256 total IP addresses). Subtracting 2 for the Network Address and Broadcast Address leaves 254 usable host addresses.
