What is a class B subnet mask?

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

What is the natural mask of class B network?

IP subnetting

	Subnet Mask	Number of Supported Hosts per Network
Class A	255.0.0.0	Over 16 million
Class B	255.255.0.0	Over 16 thousand
Class C	255.255.255.0	254

What is a class B network?

A Class B network was a network in which all addresses had the two most-significant bits set to 1 and 0 respectively. For these networks, the network address was given by the next 14 bits of the address, thus leaving 16 bits for numbering host on the network for a total of 65536 addresses per network.

What is a Class B IP range?

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.

How many IPS are in a class B?

Table 2-1 IP Addresses Available to Internet Hosts

Address Class	First Octet Range	Number of Hosts Per Network
Class A	0 to 126	16,777,214
Class B	128 to 191	65,534
Class C	192 to 223	254

How many hosts can a class B network have?

How many Class B networks are there?

16,384 possible Class B
0.0 as Class B networks. There are 16,384 possible Class B networks.

What is a Class B IP address?

Class B IP addresses, where the 1st two bits are 10, are in the range of 128.0. 0.0 to 191.255. 255.255. This class is for medium networks and has 16 bits for network and 16 bits for hosts. Class C IP addresses, where the 1st three bits are 110, are in the range of 192.0.

How many hosts can each class B network have?

65,534 hosts
With 16 bits total, 216 combinations are possible, yielding 65,536 Class B addresses. Recall that two of those numbers, the lowest and highest values, are reserved for special purposes. Therefore, each Class B address can support up to 65,534 hosts.

How do you subnet a Class B?

For the fourth octet, the mask would be 256-128=128, which is one subnet if it is used. However, if you turn the subnet bit off, the value is 0. This means that for every subnet in the third octet, the fourth octet has two subnets: 0 and 128, for example 1.0 and 1.128….Subnetting a Class B network address.

Subnet	64.0	128.0
broadcast	127.255	191.255

What is the difference between Class A Class B and Class C networks?

If the address is written in decimal format, the first number determines the address. If the first number is between 0 and 127 inclusive, the address is class A. If the first number is between 128 and 191 inclusive, the address is class B. If the first number is between 192 and 223 inclusive, the address is class C.

Is a Class B IP address private?

Reservation of IP addresses in Class B networks Networks belongs to “Class B” from 172.16. 0.0 to 172.31. 0.0 are reserved for private use and can be used inside any organization.

What does netmask 255.255 255.0 mean?

A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). If your computer is connected to a network, you can view the network’s subnet mask number in the Network control panel (Windows) or System Preference (macOS).

What is the subnet mask for Class B IP address?

The subnet mask is fixed 255.255.0.0 for a classfull class B IP address. In this IP address we have only 16 bits for host. For creating subnetting we have only 16 bits to manipulate. Lets begin the subnetting for class B network. Do not be panic by reading so many mathematical expressions in this article.

What is a Class B network in Linux?

Class B Networks (/16 Prefixes) This network is a 16-bit network prefix; its highest bit order is set to 1-0. It is a 14-bit network number with a 16-bit host number. This class defines 16,384 (2 14) /16 networks, and supports a maximum of 65,534 (2 16 -2) hosts per network.

What is the range of Class B networks?

128.0.0.0 up to 191.255.0.0 Networks can be used as Class B Networks. 16 Networks dedicated for internal usage. Up to last network… Up to the last Network’s IP Address range… Note: Some people might believe that any IP Address that start with 172 is a Private IP address, that’s Not True.

What is the meaning of 10 in a Class B network?

The left-most two bits (also called as high-order bits or most-significant bits) of the left most octet of a “Class B” network is reserved as “10”.
