Subnetting and creating subnet masks is often outsourced to consultants, but doing it yourself can be both challenging and rewarding. In the IT world, specifically in networking, there aren’t ...

Perhaps the most recognizable aspect of subnetting is the subnet mask. Like IP addresses, a subnet mask contains four bytes (32 bits) and is often written using the same dotted-decimal notation.

These bits become a tradeoff based on the network class (A, B or C). Subnet masks for a Class C network (small network) use the first 24 bits for subnet ID and the last 8 for host ID. These last 8 ...

Subnet Mask divides the IP address into two segments and informs the computer which part is the network bit and which one is the host bit. For example, if there is an IP address: 192.168.0.1 ...

Anytime you want to refer to a subnet, you point to its Network ID and its subnet mask, which defines its size. Anytime you want to send data to everyone on the subnet (such as a multicast), you ...

Here, I will explain Class A subnet masks and how to assign valid subnets and host addresses to provide flexibility in configuring your network. Info on Class B and Class C subnetting If you need ...

IPv6 addresses do not follow any type of “class” structure like IPv4 addresses did (Class A, B, C) so all IPv6 networks basically use a Variable Length Subnet Mask (VLSM). Typically the word ...

I have an Excel spreadsheet containing IP addresses and subnet masks. I need to derive the subnet of each IP address in the spreadsheet.<BR><BR>Example: IP (column A): 10.1.230.84, Subnet Mask ...

The subnet ID number is shared with the host ID. See subnet mask and subnet mask tables. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.
