TCP and IP settings How do computers communicate in a network
IP address:
11000000.10101000.11001001.10101101
subnet mask:
11111111.11111111.11111111.11100000
The subnet mask shows that the first 27 bits are the network portion of
the address, the last 5 bits are the node portion, which means there is
room for 32 addresses on this network (all numbers between 00000 and
11111 in binary).
A.2.3 IP address range
All addresses in this network share the first 27 bits. The first address in
the local network is 192.168.201.160. The last address is
192.168.201.192. In binary:
First address:
11000000.10101000.11001001.10100000
Last address:
11000000.10101000.11001001.10111111
Such a group of addresses is also called an IP address range.
A.2.4 Reserved addresses
The first and last addresses in a range cannot be assigned to computers
in your network. These addresses have special functions.
The first address in a range is also known as the network address, the
last address is the broadcast address.
Subnet masks are sometimes written down as 192.168.201.160/27,
where 192.168.201.160 is the first address (or ‘network address’) in the
range, and 27 is the number of 1s in the binary representation of the
subnet mask (this subnet mask can also be written as 255.255.255.224).
A.2.5 Gateway
If a device wants to communicate with another device it will determine if
that IP address is in the same subnet as its own IP address. If it is, it can
communicate directly with the other, if it isn’t, the situation is more
complicated; it has to communicate with another subnet.
To communicate between subnets there has to be a connection between
the 2 subnets. This connection is made via devices known as gateways.
If a device wants to communicate with a device in another subnet it
sends the information to the gateway, and the gateway takes care of the
rest of the transport.
