What Is the Default Subnet Mask for a Class B Address?

Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet.

What is the default subnet mask for a class address?

Most home networks use the default subnet mask of 255.255. 255.0. However, an office network may be configured with a different subnet mask such as 255.255. 255.192, which limits the number of IP addresses to 64.

What is the default subnet mask for a Class B address Mcq?

0.0. We know that the default mask of a class B network is 255.255. 0.0.

What is the default subnet mask number of bits for a Class B ipv4 address?

Class B Address

An IP address which belongs to class B has the first two bits in the first octet set to 10, i.e. Class B IP Addresses range from 128.0. x.x to 191.255. x.x. The default subnet mask for Class B is 255.255.

What is a Class B IP address?

Class B IP addresses are used for medium and large-sized networks in enterprises and organizations. They support up to 65,000 hosts on 16,000 individual networks. Class C addresses are most common and used in small business and home networks.

Is 255.255 255.255 IP address valid?

255.255. 255.255 represents the local broadcast address, which is only propagated within the network. This broadcast data cannot cross routers by default. That is, it is a restricted broadcast address.

What is a 255.255 0.0 subnet?

Understanding Networks and Networked Video

It is a 32-bit number that distinguishes each octet in the IP address. For example, as depicted in Table 4.9, 255.255. 0.0 is a standard Class B subnet mask, since the first two bytes are all ones (network) and the last two bytes are all zeros (host).

What is the default mask for Class B in CIDR notation?

0.0. These networks use the 255.0. 0.0 subnet mask, or /8 CIDR notation. Class B: Allows 216 host addresses on the network.

What is default mask of Class A Mcq?

Explanation: The mask 255.255. 254.0 (/23) used with a Class A address means that there are 15 subnet bits and 9 host bits.

What is the default subnet mask for a class B network quizlet?

The default subnet mask for a Class B is 255.255. 0.0.

What is a 27 subnet mask?

/27 — 8 Subnets — 30 Hosts/Subnet. Network # IP Range. Broadcast. .0.

What is a 25 subnet?

/25 — 2 Subnets — 126 Hosts / Subnet

Network # IP Range. Broadcast. .0. .1 – .126.

What is the default subnet mask of Class C?

The maximum number of hosts is achieved by using the default subnet mask for each class (i.e. by having only one subnet). Number of bits for Class C networks — 24 bit mask = 255.255. 255.0, 32 bit mask = 255.255.

What is subnet mask on router?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.

What is a mask in ipv4 addressing what is a default mask in ipv4 addressing?

Mask – It is a 32-bit binary number that gives the network address in the address block when AND operation is bitwise applied on the mask and any IP address of the block. The default mask in different classes are : Class A – 255.0.0.0. Class B – 255.255.0.0.
