The ifconfig command can change both the ip address and netmask of a network interface: ifconfig eth0 10.10.10.10 netmask 255.255.255.0 Is it possible to change the netmask of the network interface
Netmask Bit mask of ip _ address. To limit access to a single IP address, use 255.255.255.255 for the subnet mask. 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

Aug 25, 2002 Subnet Mask Calculator - aboutmyip.com Broadcast: IP broadcast addresses are used for single-packet one-to-everyone delivery. A sending host addresses the IP packet using a broadcast address and every node on the sending node's network segment receives and processes the packet. IP broadcast addresses can be … IP Calculator / IP Subnetting
Enter your netmask (s) in CIDR notation (/25) or dotted decimals (255.255.255.0). Inverse netmasks are recognized. If you omit the netmask ipcalc uses the default netmask for the class of your network. Look at the space between the bits of the addresses: The bits before it are the network part of the address, the bits after it are the host part.
