What is the default subnet mask for ip address 192.168.1.254?

That would be a class E network, E networks do not have defines subnet masks or networks. Just a range (240.0.0.0 - 255.255.255.255).


How you subnet ip address using class b?

Same as subnetting any other class, or a classless network. From the bits originally reserved for the host (16 bits, in the case of a class B address), you "borrow" some bits, that is, you use them to specify the subnet. The remaining bits specify an individual host within a subnet.


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

Given a Class C network: 200.1.1.0 We want 5 subnets, each with 30 hosts on it. How many bits to borrow ? How many bits to leave? What is the subnet mask? ( in dot notation and in CIDR notation)


What class has subnet mask 225.225.225.0?

If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.


What is the maximum number of bits that can be borrowed to create a subnet for a Class C network?

You can borrow 6 bits. Which would create a 255.255.255.252 subnet mask, but this subnet only contains 2 usable IP addresses. 7 bits would be 255.255.255.254, but that subnet is too small to have any use in the real world.


Which subnet mask should be used for a class B network that is divided into subnets that will accommodate between 800 hosts and 1000 hosts?

255.255.252.0

255.255.252.0


What is the default subnet mask for the IP address 176.43.52.18?

255.0.0.0 for a class A correct. but why? well, 10.10.0.0 is a class a network and all class "a" networks use a default subnet mask of 255.0.0.0. the range of class "a" networks is 1-126.


What is the correct subnet mask to use for a class-B address to support 30 networks and also have the most hosts possible?

This question is unanswered.


What is the subnet of 66.237.178.241?

The default subnet would be 255.0.0.0 (class A)


What class has subnet mask 255.255.255.0?

The address you gave is not an IP address; it has the appearance of a subnet mask. It could be a class A or class B subnet mask.
