[Part 1 of this article begins with an overview of IP addressing. Part 2 reviews the network/host boundary and examines the IPv4 address in detail. Part 3 looks at the IPv6 header and address, as well ...

How to subnet. To subnet properly there are topics you need a basic understanding of: binary (base-2) numbers, and classful networks.The idea with classful networks is essentially that IPv4 ...

IPv4 SUBNETTING BASICS. Before talking IPv4 subnetting, let me mention that there are two IP addressing schemes. IPv4 uses the dotted decimal notations we have been talking about, while IPv6 uses an ...

IPv4 subnetting causes routing tables to contain smaller and smaller subnets and increase memory and CPU requirements on backbone routers and even enterprise routers (for multi-homed companies).

Subnetting in IPv4 The IP address space was originally classful. (Of course, they didn't know it was classful back then—it was just the IP address space). As such, it contained a number of special ...

While IPv4 and IPv6 are very much alike to users and applications; "on the wire," the protocols are completely separate and don't interact. ... (the equivalent of the IPv4 subnet mask).

MORE IPv4 SUBNETTING BASICS. Consider an analog clock. Start the second hand at 12:00 and follow it clockwise around the dial. ... The new subnet mask is 11111111.11111111.11111111.10000000. Borrowing ...

IPv4 (version 4) addresses are formatted in a "dotted-decimal octet" format like "192.168.0.3." Subnet masks have the same format, but are typically displayed as "255.255.255.0" on a local area ...

In IPv4, every IP address comes with a corresponding subnet mask. IPv6 also uses subnets, but the subnet ID is built into the address. In an IPv6 address, the first 48 bits are the network prefix.
