255.255.255.0 is the subnet mask for which class of IP network?
Class C network if you are not subnetting.
No of host in class A?
The number of hosts in a classfull class A network with no subnetting is 16,777,214
What are the advantages of Class A network over Class B and Class C?
A class A network has more IP addresses - you can connect more hosts on it.A class C network has 256 IP addresses (of which you can use 254), a class B network about 65,000, a class A network about 17 million.More specifically, a Class A network can have 16,777,214 usable host addresses per network whereas a Class B network can have 65,6534 usable host addresses per network.Another advantage is the ridiculous amounts of subnetting you can do. For example, in a Class C network, you can't borrow the same number of bits as you can with a Class A because you only have the last octet to work with for the host portion. With a Class A network, the last three octets are the entire host portion, so you have 24 bits to work with for subnetting (technically 23 since you can't subnet down through all available bits and have no bits left for hosts =p). Due to the amount of subnets you can have and the 16+ million hosts you can potentially have on the same network, Class A networks are reserved for super big applications (ISPs and gigantic companies).
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.
If you have a class b network 172.121.225.0 and you want to do subnetting of 130 networks how many bits are used for subnetting?
As we are using a class B network for the Subnetting and we have to make a total of at least 130 subnetworks...so, class B default subnet mask is 255.255.0.0 or 16 bits for networkingand we have to make 130 sunets. so it will come under the block size of 256 or we need 8 bits more to make 130 subnets.so our answer is 16+8=24ie, we will use subnet mask of 255.255.255.0 for this class B address.
network portion of these addresses: 209.240.80.78?
This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.
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 is the default subnet mask for IPv4?
The submask indicates the division between the network id and the host information in an ipV4 address. The default subnet mask indicates the presence of a class A, B, or C based network (the default) without subnetting.
What is the network portion of 177.100.18.4?
This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.
How many bits comprise the network portion of a class c address?
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.
If internet protocol is 135.210.195.112 what is the subnet mask?
It depends on whether you are using a default subnet mask or you are subnetting the class B network. A default subnet mask would be 255.255.0.0, but if you are subnetting the last 2 octets in the subnet mask could be anything (up to 255 per octet).
Difference between supernetting and subnetting?
SUBNET: subnet is a group of networks having same network id. subnet increase the number of hosts with same network address, as result it reduces the wastage of addresses. In subnetting bits of hostId will be captured by networdId. SUPERNET: supernet makes all the hosts with in a range of network address belong to a same group. This reduces the entries in the network address table. Supernetting combines the octets of the address.
