Examples:
The subnet 192.168.0.0 with an implied netmask of 16 valid bits
(sometimes used in the netmask form 255.255.0.0)
192.168
The subnet 192.168.112.0/21 with a netmask of 21 valid bits (also
used in the netmask form 255.255.248.0)
192.168.112.0/21
A subnet with 32 valid bits is the equivalent to an IP address and a subnet
with zero valid bits (0.0.0.0/0) matches any IP address.
B.4
IP Address
An IP address represents a fully qualified internet address in numeric
(dotted quad) form. Usually, this address represents a host, but the
address does not necessarily have to have a DNS domain name.
Example:
192.168.123.7
B.5
Hostname
A hostname is a fully qualified DNS domain name, which can be resolved
to one or more IP addresses via the domain name service. It represents a
logical host (in contrast to domains) and it must be resolvable to at least
one IP address, or to a list of hosts with different IP addresses.
Examples
server.example.com
smtp.example.com
An IP address does not need to be resolved by the DNS system,
so it can result in more effective performance.
