Client group management

You can select an existing client or add a custom one by typing into the field above and confirming your entry with ⏎. Multiple clients can be added by separating each client with a space or comma. Clients may be described either by their

1. IP addresses (IPv4 and IPv6 are supported),
2. IP subnets (CIDR notation, like 192.168.2.0/24), their
3. MAC addresses (like 12:34:56:78:9A:BC), by their
4. hostnames (like localhost), or by the
5. interface they are connected to (prefaced with a colon, like :eth0).

The first match (from top to down) wins. Note that client recognition by host name or interface recognition as the two latter may only be available after some time. Furthermore, MAC address recognition only works for devices at most one networking hop away from your Pi-hole.
