How many valid host addresses are available on class B network that is not subnetted?
65,534
Assuming no subnetting what are valid Class B host addresses?
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.
What are the valid class C ip addresses that can be assigned to hosts?
Class C IP addresses range from 192.0.0.0 to 223.255.255.255. However, the first address in each subnet is reserved as the network address, and the last address is reserved for the broadcast address. Therefore, valid Class C addresses that can be assigned to hosts typically range from 192.0.0.1 to 223.255.255.254, excluding the network and broadcast addresses within any specific subnet.
Which IP addresses are defined by RFC 1918 as private addresses?
"The RFC 1918 private network numbers are 10.0.0.0, Class Bs between 172.16.0.0 and 172.31.0.0 inclusive, and all Class C networks that begin with 192.168. All addresses that begin with 127 are reserved, but not as valid private IP addresses."
What is the maximum number of bits that can be borrowed with class b?
The maximum number of host bits that can be borrowed from a class A address is 22 (technically you could borrow 23 but the resulting network would be useless). A class A address uses 8 bits for its network address and 24 bits for its host addresses. Class A uses a subnet mask of 255.0.0.0 You can only borrow 22 bits (instead of 24) because a valid network requires 4 addresses: A network address, two host addresses and a broadcast address. These networks would result in 30 bits used for the network address and 2 bits used for the host addresses. These networks use a subnet mask of 255.255.255.252
How many valid IP addresses can you use in a class C network address if you are using 24 bits for the default subnet mask?
You can use up to 254 devices in this case.
Why is it unlickely that you will find the IP address 192.168.250.10 on the Internet?
It is unlikely that you will find the IP address 192.168.250.10 on the internet because the .10 represents the number of host connected to an individual network. Also, IEEE recommends that the following IP addresses be used for private networks: 10.0.0.0 through 10.255.255.255 Class A 172.16.0.0 through 172.31.255.255 Class B 192.168.0.0 through 192.168.255.255 Class C
Is 191.76.43.10 a valid routable class C address?
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.
How many valid host addresses are available on an IPv4 subnet that is configured with a 26 mask?
An IPv4 subnet with a /26 mask has 64 total IP addresses (2^(32-26)). However, 2 addresses are reserved: one for the network address and one for the broadcast address. Therefore, the number of valid host addresses available is 64 - 2 = 62.
Is 255.255.0.255 a valid Class A address?
No, 255.255.0.255 is not a valid Class A address. In fact, it is a broadcast address used in Class B networks. Class A addresses range from 1.0.0.0 to 126.255.255.255, and the highest address in this range is 126.255.255.255. Additionally, the address 255.255.255.255 is reserved for the limited broadcast address, not for any specific class.
How many host can you have for 10.20.50.0 subnet mask 255.255.255.0?
253. Valid addresses would be from 10.20.50.1 to 10.20.50.254 10.20.50.0 is the network address. 10.20.50.255 is the network broadcast address. Any network with a subnet mask of 255.255.255.0 will support 253 hosts.
How many ip addresses are there in a class A?
There are 2^24 host in class A but (2^24)-2 hosts are valid since the first and last address are reserved .
