Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet. The address 172.16. 52.63 is a class B address.
What is a Class B IP address example?
Class B Network
The first 16 bits (known as two octets) help you identify the network. The other remaining 16 bits indicate the host within the network. An example of Class B IP address is 168.212. 226.204, where *168 212* identifies the network and *226.204* helps you identify the Hut network host.
How do I find my class B network?
Class A addresses are for large networks; they use 8 bits for the network ID and 24 bits for the host ID. Class B (128.0. 0.0 to 191.255. 255.255) for general use.
IP Addresses.

| Class B Subnet Mask | 255.255.0.0 | 11111111.11111111.00000000.00000000 |
How do I assign a Class B IP address?
A class B network number uses 16 bits for the network number and 16 bits for host numbers. The first byte of a class B network number is in the range 128-191. In the number 129.144. 50.56, the first two bytes, 129.144, are assigned by the InterNIC, and comprise the network address.
How many addresses are there in a class B subnet?
Class B Address
x.x. The default subnet mask for Class B is 255.255. x.x. Class B has 16384 (214) Network addresses and 65534 (216-2) Host addresses.
What is a class B subnet?
Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet. The address 172.16. 52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive.
What is a class B network used for?
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.
Which criteria identify a Class B address?
If the address is written in binary format, the leftmost bits in the address will define the class. If the first bit is 0, the address is a class A address. If the first bit is 1 and the second bit is 0, the address is a class B address.
Which address class does not need subnet mask?
0.0 to 255.255. 255.255. Just like our Class D multicast addresses, these addresses do not have a default subnet mask.
What is class in IP address?
An IPv4 address class is a categorical division of internet protocol addresses in IPv4-based routing. Separate IP classes are used for different types of networks. Some are used for public internet-accessible IPs and subnets, that is, those networks behind a router (as in classes A, B and C).
What is the default subnet mask of Class B?
255.255.0.0
Consequently, the default subnet mask for Class B is 255.255. 0.0. In addition, Class C IP addresses are normally assigned to a very small-sized network. Their IP addresses range from 192 to 233 and their default subnet mask is 255.255.
How do you subnet a Class A?
Valid subnet address: To figure out the valid subnet address, simply subtract the subnet mask from 256. For example, if you had a Class A mask of 255.240. 0.0, the equation would be 256-240=16.
The first available subnet is:
- Subnet: 10.0. 0.0.
- Broadcast: 10.0. 127.255.
- Valid host range: 10.0. 0.1 through 10.0. 127.254.
What is subnet mask for IP address?
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 the class B private IP address range?
Class B: 172.16. 0.0 to 172.31. 255.255.
How many hosts are in a class B network?
Range
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 |
What is a Class C subnet?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
How do subnets work?
Subnetting works by applying the concept of extended network addresses to individual computer (and another network device) addresses. An extended network address includes both a network address and additional bits that represent the subnet number.
How do I find my subnet address?
The Subnet address is identified by all 0 bits in the Host part of the address. The first host within the subnet is identified by all 0s and a 1. The last host is identified by all 1s and a 0. The broadcast address is the all 1s.
What is a class B network address?
A class B network is a type of network in the now-defunct classful networking architecture.Class B networks have IP addresses between 128.0. 0.0 and 191.255. 255.255. The Classful networking system has been superseded by CIDR (Classless Inter-Domain Routing) since 1993.
Is a Class B IP address private?
Reservation of IP addresses in Class B networks
An important IP address reservation in Class B IPv4 addresses is private networks, from 172.16.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.
How do I know if my IP is Class AB or C?
How to identify the IP class from a given IP address?
- If it begins with 0, then it’s a Class A network.
- If it begins with 10, then it’s a Class B network.
- If it begins with 110, then it’s a Class C network.
- If it begins with 1110, then it’s a Class D network.
- If it begins with 1111, then it’s a Class E network.
