Default Gateway
The default gateway address is your router or switch
IP address that does the address forwarding in case
the IP address of the receiver in not the subnet of the
sender.
IP Address
An IP (Internet Protocol) address is a unique identifier
for a node or host connection on an IP network. An IP
address is represented as 4 decimal values separated
by decimal points. This is known as "dotted decimal"
notation. Example: 140.179.220.200The IP address
and the subnet mask determine which part belongs to
the network address and which part belongs to the
node address.
Subnet mask
To have a subnet in an IP Network can be done for a
variety of reasons, including organization, use of
different physical media (such as Ethernet, FDDI,
WAN, etc.), preservation of address space, and
security. The most common reason is to control
network traffic. In an Ethernet network, all nodes on
a segment see all the packets transmitted by all the
other nodes on that segment. Performance can be
adversely affected under heavy traffic loads, due to
collisions and the resulting retransmissions. A router is
used to connect IP networks to minimize the amount of
traffic each segment must receive.Applying a subnet
mask to an IP address allows you to identify the
network and node parts of the address. The 1s in the
mask represents the network bits, and the 0s
represents the node bits. Performing a bitwise logical
AND operation between the IP address and the
subnet mask results in the Network Address or
Number.
