The address class is determined from the high-order bits of the

first byte.

• The first byte of a Class A address contains a zero and seven

network bits. The next 24 bites identify the host.

• A Class B address contains a one, a zero, 14 network bits and

16 host bits.

• Finally, a Class C address contains a one, a one, 22 network

bits and 8 host bits.

The echo sounder computer, GPT transceiver(s) and other

computers that communicate on the Ethernet must reside on the

same network. This requirement is met only if the host part of

the address differs.
