IP Reg is a IPAM tool to keep track of assets, nodes (IP addresses, MAC addresses, DNS aliases) within different subnets, over different locations or even VLAN's. Written in PHP, used with a MySQL-database to have a unique insight in your local network.
You can not select more than 25 topics Topics must start with a letter or number, can include dashes ('-') and can be up to 35 characters long.
