Network address

The given network address has to be a valid IPv4 subnet without netmask - for example


The netmask or subnetmask of an IPv4 network is a descriptor for the size of the network. It also can be used to divide a network into two or more networks. The used subnetmask can be specified in dotted-decimal notation (e.g. “/24”) or in classless_inter-domain_routing (e.g. “”).


As an optional feature you can add a remark.

On the listing, some more items are displayed. The column “Used” shows how often a created network entry is used as part of a network group or firewall rule.

The yellow pencil offers the ability to edit the content of an entry. With the trash icon an existing and unused entry can be deleted.
