- Subnet Masks
- What are the difference between class A, B, and C subnet masks? Are there any limitations of Classless Interdomain Routing CIDR?The default masksare;A=255.0.0.0B=255.255.0.0C=255.255.255.0There are actually 5 classess but only three are used for normal routing and each of the three have a private or NAT address range. Here is a...

- Expand your network by supernetting IP addresses
- Put simply, supernetting a TCP/IP network address is the opposite of subnetting it. Supernetting is also known as CIDR classless interdomain routing as defined by RFCs 1517, 1518, 1519, and 1520. In IPv4, CIDR is one way of attempting to manage the shortage of TCP/IP addresses until IPv6 takes over. Supernetting...
