This is why subnetting comes in handy: subnetting narrows down the IP address to usage within a range of devices. Because an IP address is limited to indicating the network and the device address, IP addresses cannot be used to indicate which subnet an IP packet should go to. Routers ...
A subnet, or subnetwork, is a logical subdivision of an IP network into network segments. With subnets, large networks can be subdivided into smaller ones.
This is where subnet masks come back in. If you’ve “borrowed” bits from the host portion of the IP address, it can be hard to tell where the network portion ends and the host portion begins. With a subnet mask, you can specify which portions of the subnet are the network and whic...

For example, in the following figure, VLAN 2 contains 10 hosts. The VLAN is assigned the subnet 10.1.1.0/28, which provides 16 IP addresses. Of these addresses, 10.1.1.0 is the subnet ID, 10.1.1.15 is the directed broadcast address, and 10.1.1.1 is the default gateway address. The rema...
The default VLAN of a trunk interface is defined as the native VLAN by some vendors. When a trunk interface receives an untagged frame, it adds the native VLAN tag to the frame. Hybrid Interface A hybrid interface can connect to a user terminal (such as a host or server) or network dev...
Why is IPsec important? Security protocols like IPsec are necessary because networking methods are not encrypted by default. When sending mail through a postal service, a person typically would not write their message on the outside of the envelope. Instead, they enclose their message inside the ...
A VLAN is identified on network switches by a VLAN ID. Each port on a switch can have one or more VLAN IDs assigned to it and will land in a default VLAN if no other one is assigned. Each VLAN provides data-link access to all hosts connected to switch ports configured with its VLAN...

What Is a Subnet Mask? Computers in a subnetwork have IP addresses that all start with the same prefix. This prefix can vary in length, depending on how big the network needs to be. A subnet mask identifies the length of this prefix and, therefore, the size of the network. ...
