If an ip address has the number 194 in the first octet, it is a class _______ address.
If an IP address has the number 194 in the first octet, it is a class C address.
If you're working with IP addresses, it's important to know the different classes. An IP address can be classified as a Class A, B, or C address. If the first octet of an IP address is 1-126, it's a Class A address. If the first octet is 127, it's a Class B address. And if the first octet is 128-191, it's a Class C address.
The number in the first octet tells us what class the address is in. For example, an address with the first octet of 194 is a Class C address. Class C addresses are most commonly used for home and small office networks.
Knowing the class of an IP address is important because it determines the range of addresses that can be used. For example, Class A addresses can be used for networks with up to 16 million hosts, while Class B addresses can be used for networks with up to 65,000 hosts.
So, when you're working with IP addresses, be sure to keep the different classes in mind. Knowing which class an address is in will help you understand what range of addresses can be used.
