Subnets When an IP network address for a particular network class is assigned to an organization, no provision is made for more than one network being present at that location. Local network administrators use subnets to partition a network into several different subnetworks. Splitting a network into subnets can result in better performance and improved use of limited network address space. Subnet mask The subnet mask is a mechanism used to divide a single IP network into several different subnetworks. For a given network class, a portion of an IP address that would normally be used to identify a node is used, instead, to identify a subnetwork. A subnet mask is applied to each IP address to specify the portion used for subnetworks, and the portion used to identify the node. Gateways Gateways (routers) are used to connect networks together. Gateways are devices that act as translators between systems that do not use the same communication protocols, data formatting, structures, languages, or architectures. Gateways repackage the data packets and change the syntax to match that of the destination system. When networks are divided into subnets, gateways are required to connect one subnet to another. Default gateway The default gateway is the IP address of the gateway or router that moves packets between networks. If multiple gateways or routers exist, then the default gateway is typically the address of the first, or nearest, gateway or router. If no gateways or routers exist, then the default gateway will typically assume the IP address of the network node (such as the workstation or product). 42 Chapter 5 Connectivity ENWW

Subnets

When an IP network address for a particular network class is assigned to an organization, no provision

is made for more than one network being present at that location. Local network administrators use

subnets to partition a network into several different subnetworks. Splitting a network into subnets can

result in better performance and improved use of limited network address space.

Subnet mask

The subnet mask is a mechanism used to divide a single IP network into several different subnetworks.

For a given network class, a portion of an IP address that would normally be used to identify a node is

used, instead, to identify a subnetwork. A subnet mask is applied to each IP address to specify the

portion used for subnetworks, and the portion used to identify the node.

Gateways

Gateways (routers) are used to connect networks together. Gateways are devices that act as translators

between systems that do not use the same communication protocols, data formatting, structures,

languages, or architectures. Gateways repackage the data packets and change the syntax to match

that of the destination system. When networks are divided into subnets, gateways are required to

connect one subnet to another.

Default gateway

The default gateway is the IP address of the gateway or router that moves packets between networks.

If multiple gateways or routers exist, then the default gateway is typically the address of the first, or

nearest, gateway or router. If no gateways or routers exist, then the default gateway will typically assume

the IP address of the network node (such as the workstation or product).
