A client side Wireguard "AllowedIPs" calculator. This can also be used as a generic tool to exclude a subset of CIDR's from a larger scoped CIDR.
Any change you make to Allowed IPs or Disallowed IPs is persisted in the url hash so you can easily bookmark calculations or send them to others. For example, allow 0.0.0.0/0, disallow 1.1.1.1 and 8.8.8.8.
