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

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.
