DETERMINE IP ADDRESS FROM MAC ADDRESS

Computers can determine IP addresses from MAC addresses
using DHCP and formerly other protocols like RAddress Resolution
Protocol and Address Resolution Protocol. DHCP Manages network
configuration by registering and updating IP addresses and DNS names.

There is no universal mechanism for an end user to determine an IP
address given a known MAC address, although it can be done in certain
specific situations. The Address Resolution Protocol (Formerly known as
ARP) allows a host to find the MAC address of a node with an IP address
on the same physical network, when given the node’s IP address. To make
Address Resolution Protocol efficient, each computer caches IP-to-MAC address mappings to eliminate repetitive Address Resolution Protocol broadcast requests.

The Address Resolution Protocol tool allows a user to view and
modify Address Resolution Protocol table entries on the local computer.
The Address Resolution Protocol command is useful for viewing the
Address Resolution Protocol cache and resolving address resolution
problems.

Some corporate networks solve the problem of universal MAC-to-IP
address mapping by installing special management software agents on all
computers. These software systems, based on Simple Network Management
Protocol (SNMP), which includes a capability called
network discovery. These systems forward messages out to the agent on
every network device a request for both the IP and MAC addresses of
that device. The system receives then stores the results in a master
table separate from any individual Address Resolution Protocol cache.

With Internet Protocol, network discovery is often implemented using ping
commands and internet Control Message protocol (ICMP) messages. Pinging
a remote device from any client will trigger an Address Resolution
Protocol cache update. Typically this update occurs only in the Address
Resolution Protocol cache of the LAN routers and not on the originating
client, however.
