A class B address range is all the addresses that start with binary 10, or decimal 128-192. As originally defined, the first two bytes (octets) indicate the network; the last two bytes are reserved for the host. That is, a class B network has about 65,000 available addresses.
128-191
128 to 191
In a Class B range, the first network address would be 128.0.0.0 and the last network address would be 191.255.0.0 Class B addresses are assigned to medium-sized to large-sized networks with up to 65,534 hoasts per network.
No, because the range for class C addresses is 192 - 223, and the first octet of the address 191.76.43.10 is a class B address.
class b
APIPA addresses are in the range 169.254.0.1 through 169.254.255.254. These would be in the Class B address range.
Since 157.54.4.201 falls in the class B address range the default subnet mask would be: 255.255.0.0 128 - 191 is a class B address.
The entire 127 range (127.0.0.1 to 127.255.255.254) is considered the LOOPBACK address range, and is in the class A network. This address range or block is reserved just for local testing.
what companies have class B address
Class B, if you are referring to classful addressing schemes.
192.168.x.x is an IP address in the private IP address range.
A classful class B network has a network range of 128 - 191. For host addresses, anything that is legal for an IP address in the last 2 octets would be a valid host address for a class B with no subnets.
