ADDRESS RESOLUTION WITH CLOSED-FORM COMPUTATION
For networks use reliable addressing, it is possible to select an address that creates closed-form address resolution possible. A resolver is used to compute a mathematical operation that maps an IP address to a machine address.
When a device connects to a network that uses configurable address, the local network administrator must select a hardware address as well as an IP address. The two values can be selected to create address resolution trivial. Let's take an example.
EXAMPLE:
Consider a configurable network number:
220.123.5.0/22
The IP address of first receiver = 220.123.5.1
Hardware Address = 1
The IP address of second receiver = 220.123.5.2
Hardware Address = 2
The IP address of router = 220.123.5.102
Hardware Address = 102
A simple Boolean 'and' operation can calculate the computer's hardware address.
Hardware Address = ip_address & 0xff
ROUTING TABLES AND ADDRESS MASKS Additional information is saved in routing table. Destination is kept as network address. Next hop is saved as IP address of router. Address m
