CIDR (Classless InterDomain Routing)
IP netmasks and CIDR are notations which aggregates several IP addresses to form
one address range. A range of consecutive addresses is treated as a network.
The CIDR scheme reduces, for example, the routing tables stored in routers by means
of a postfix in the IP address. With this postfix, a network and the networks lying below it
can be denoted in a summarized form. The method is described in RFC 1518.
To advise a range of IP addresses to the SINAUT MD740-1, e.g. when configuring the
firewall, it may be necessary to give the address space in CIDR syntax. The following
table shows the IP netmask on the left, with the corresponding CIDR syntax on the far
right.
