How do you find the subnet of a class B?
2-2=510 subnets. 2-2=126 hosts per subnet. For the third octet, the mask would be 256-255=1, 2, 3, 4, 5, 6, etc. For the fourth octet, the mask would be 256-128=128, which is one subnet if it is used….Subnetting a Class B network address.
| Subnet | 64.0 | 128.0 |
|---|---|---|
| last host | 127.254 | 191.254 |
| broadcast | 127.255 | 191.255 |
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.
Is 192.168 a Class B?
192.168 is class C and 172.16 is class B, Class C networks are not Class B networks.
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 The Classful networking system has been superseded by CIDR (Classless Inter-Domain Routing) since 1993.
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.
What is the range of class B IP address?
Designing Your IP Addressing Scheme
| Class | Range | Network Address |
|---|---|---|
| A | 0-127 | xxx |
| B | 128-191 | xxx . xxx |
| C | 192-223 | xxx . xxx . xxx |
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.
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.
What is the class B private IP address space?
Class B: 172.16. 0.0 to 172.31. 255.255.
Which of the following is a Class B host address?
Class B Address 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 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. Class C addresses are most common and used in small business and home networks. These support up to 256 hosts on each of 2 million networks.
What part of a Class B IP address identifies the network?
first 16 bits
In a Class B network, the first 16 bits are the network part of the address. All Class B networks have their first bit set to 1 and the second bit set to 0. In dotted decimal notation, that makes 128.0. 0.0 to 191.255.
What is the subnet mask for Class B?
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. Class C networks use a default subnet mask of 255.255.255.0 and have 192-223 as their first octet.
What is a private Class B IP address?
The Private Class B range of IP addresses fall into 16 subnets. These were provided so that an organization could have up to 65,534 hosts on a network and have up to 16 networks. The Private Class C range of IP addresses is designed to support 254 networks of up to 65,534 hosts.
How do you make a subnet mask?
A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host address. Subnet Mask is made by setting network bits to all “1”s and setting host bits to all “0”s. Within a given network, two host addresses are reserved for special purpose, and cannot be assigned to hosts.
What is the default subnet mask?
The subnet Masks indicate which portion of an IP address denotes the network and which portion denotes the host. The subnet mask for class C IP addresses is 255.255.255.0 and is the default subnet mask for many computers and network routers.
