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.
Figure 2-4. Sample Hardware Address
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
