Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address or MAC address. The first three
bytes of the Ethernet address are fixed and read 00-20-4A, identifying the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit. The following
sample shows a hardware address:
00-20-4A-14-01-18
or
00:20:4A:14:01:18
IP Address
Every device connected to an IP network must have a unique IP address. This address references
the specific unit.
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination and source IP
address, and a destination and source port number. For example, a Telnet server commonly uses
port number 23.
