consists of a network number and a host number. There are three types of address
assignment depending on the number of hosts.
(i) Class A. (The high-order one bit of the network number is set to 0.)
(ii) Class B. (The high-order two bits of the network number are set to 10 in binary.)
(iii) Class C. (The high-order three bits of the network number are set to 110 in binary.)
An original number is set for each SV.LINK ROM.
