Answer 1

The correct answer is 1000.100.10.1.

Key Points

A network interface on a system is uniquely identified by its 32-bit IPv4 address.
The format of an IPv4 address is typically four 8-bit fields separated by periods, printed in decimal digits.
A byte of the IPv4 address is represented by each 8-bit field.
Dotted-decimal format is a common name for this way of expressing the bytes of an IPv4 address.
The network component and the host part are the additional divisions made in the IPv4 address's bytes.
Each octet in IPv4 address can have a value from 0 to 255, but in option 4 the first octet value is 1000 which is not valid. Consequently, it can not be a valid IPv4 address.

Important Points

The unique number allocated to the network is specified in the network component.
The allocated class of the network is also identified by the network component.
The portion of the IPv4 address that you give to each host is known as the host part.
This machine on your network is identified by the host part specifically.
