About this tool
The PixelForge IP Address Validator checks whether an IP address string is valid IPv4 or IPv6 format and provides additional information including address class, private/public status, loopback/multicast classification, and CIDR notation validation. It is useful for validating user input in forms, debugging network configuration, and verifying IP addresses in log files or configuration files.
Frequently Asked Questions
IPv4 dotted-decimal (192.168.1.1), IPv4 CIDR notation (192.168.1.0/24), IPv6 full notation (2001:0db8:85a3:0000:0000:8a2e:0370:7334), and IPv6 compressed notation (2001:db8::1) are all supported.
Private IP addresses (10.x.x.x, 172.16โ31.x.x, 192.168.x.x) are used within private networks and not routed on the public internet. Public IPs are globally routable.
Enter the IP address with its prefix length (e.g., 192.168.1.0/24) and the tool will validate the notation and show the network range.
127.0.0.1 (IPv4) and ::1 (IPv6) are loopback addresses that refer to the local machine. They are used for testing network software without leaving the device.
Enter one IP address per line to validate a list. The tool checks each one and reports valid/invalid status for each entry.
