URL & Network Tools

Everything about addresses on the web and on networks. Take URLs apart, build and decode query strings, normalise and de-duplicate URL lists, map redirects for a migration and check canonical tags. Plan IPv4 subnets, convert between CIDR blocks and ranges, calculate masks, network and broadcast addresses and ACL wildcards, and see how public resolvers answer for your domain.
