Question

What is the 199th address in the 220 (2 ^ 20) block of Class C?

Answer 1

IP Address:

An IP address is an identifier or label used to identify a machine on the internet or a particular network. Each of the devices on the internet must have an IP address for identification.

IPv4 is the first version of Internet Protocol that uses a 32-bit address and this protocol is most widely used.

Total number of IP address supported by IPv4 = 2³²

The netmask and subnet mask is used to divide the IP address.

Classful Addressing:

In classful addressing, an IP address is related to a class and we need to purchase a class of the IP addresses as per the requirement.

Address class:

Class A:

The range of the first octet: 0 to 127

Subnet mask = 255.0.0.0

Class B:

First octet range: 128 to 191
Subnet mask = 255.255.0.0

Class C:

First octet range: 192 to 223

Subnet mask = 255.255.255.0

Here, the first 24 bits are used for network id, and the last 8 bits are used for host id.

The first block of class C address is = 192.0.0.0

The second block of class C address is = 192.0.1.0

The third block of class C address is = 192.0.2.0

The (2 ^ 20) block of class C address is = 207.255.255.0

The first address of the (2 ^ 20) block of class C is = 207.255.255.0

The second address of the (2 ^ 20) block of class C is = 207.255.255.1

The 199th address of the (2 ^ 20) block of class C is = 207.255.255.198
