![]() Class C has an IP range of 192.0.0.0 – are a few primary features of SolarWinds Port Scanner. However, the host identifier “0” is reserved for the IP address designated to the network, and 255 belongs to the IP address designated to the broadcast address, leaving 254 network nodes for other devices. This is because a byte of data is equal to 8 bits, or 8 “binary digits.” With a bit limited to representing either 0 or 1, an 8-bit piece of data allows for a maximum of (256) variations. Since Class C IPv4 address allocates one byte to the host identifier, this tier of IPv4 network can only support a maximum of 254 hosts. Class C IPv4 addresses – All Class C addresses start with 110. ![]() Class B can produce tens of thousands of node address variants and is primarily used in medium-sized networks. Class B IPv4 addresses – If the first two bits are 10, the IPv4 address is Class B.Class A is typically used in large organizations as it can generate millions of unique node variations. Class A IPv4 addresses – If the first bit of an IPv4 binary address is 0, then the address is a Class A type.The number of nodes a network will need to support determines the exact structure of the IPv4 address, which is further classified into different address classes. ![]() Four times larger than an IPv4 address, an IPv6 address contains 128 bits in total, written in hexadecimal, and punctuated by colons rather than periods.
