Wildcard mask - Wikipedia A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, they are used in several places, for example: . To indicate the size of a network or subnet for some routing protocols, such as OSPF.; To indicate what IP addresses should be permitted or denied in access control lists (ACLs).; At a simplistic level a wildcard mask can CIDR notation explained: CIDR format,CIDR table and 255.255.255.0 ≙ 11111111 11111111 11111111 00000000. In CIDR notation, this (class C) subnet mask would be /24, since the first 24 bits determine the network component of the IP address. It’s possible to not only to fill octets completely with ones or zeros, but also to create more flexible subnetsusing VLSM. Netmask table 'x' in netmask '255.255.255.x' is 256 - number of IP addresses in the subnet. In slash-notation, the netmask is '/y', where y = 32 - n, and 2ⁿ is the number of addresses in the subnet.
