Identify the class of an IP address based on the network number?
In classful addressing, the class of an IP address can be determined by the value in the first octet: 0 - 126 class A 128 - 191 class B 192 - 223 class C
What is the motivation behind using a custom subnet mask versus the default subnet mask?
A default subnet mask gives you classful addressing on octet boundaries. A non-default subnet mask implies that you are subnetting a larger network into several smaller ones.
What is the network broadcast address for a Class C address of 192.168.32.0 with the default subnet mask?
The broadcast address for a class C network will always end in 255, in other words the fourth octet of the IP address will always be 255 (assuming your using classful addresses). For example, the broadcast address of the 192.168.1.0 /24 network is 192.168.1.255
What is classful network?
classfull netwok means all range of IPs have the same of subnetmask classless network means there is different in subnetmask of networks for examble i have two network connected through routers the first network ip is 192.168.2.0 255.255.255.192 the secound network ip is 10.1.2.1.0 255.255.255.240 for more information contact me on monkez_3@hotmail.com
How does a router running a ripv1 determine the subnet mask of the routes that are recived in routhing updates?
RIPv1 is classful and will use the proper network mask based on the leading octet. For example 192.168.20.0 would have a mask of 255.255.255.0 because it is a class C
Give an example of a classful subnet mask give an example of a classless subnet mask?
Subnet masks that use either all ones or all zeroes in an octet are called classful subnet masks. 255.255.255.0 (11111111.11111111.11111111.00000000), 255.255.0.0 (11111111.11111111.00000000.00000000), 255.0.0.0 (11111111.00000000.00000000.00000000)
How tocalculate subnet mask address?
Calculating a subnet mask depends on whether you are using the default, classful mask or a true subnet mask to divide a network into smaller pieces.The defaults are on octet boundaries (every 8 bits):255.0.0.0 class A network255.255.0.0 class B network255.255.255.0 class C networkAny other type of subnet mask with 4 octets (iPV4) can use combinations of those with any octet value from 0 - 255. No number may be larger than 255.Calculating other subnet masks would be based on how many subnets you want in the network. You could have values such as:255.192.0.0255.255.248.0.0255.255.255.252The first octet must at least be 255. The other octets may change, based on whether it is a classful default network or it is being subnetted.

Which class of IP addresses is the following address in 10.10.252.123?
That would be a Class A IPv4 address.A good way to memorize the three primary classes in classful routing is always know the ranges of the first octet for a classful IP address. An even easier way is to convert the first octet to 8-bit binary and examine the first few bits.First Octet > [10] < .10.252.123 (in binary: [00001010])Class A: 0-127 (the leading bit of the address is always 0)Class B: 128-191 (the leading bits of the address are always 10)Class C: 192-223 (the leading bits of the address are always 110)Class D: 224-239 (the leading bits of the address are always 1110)Class E: 240-255 (the leading bits of the address are always 1111)
How to use 172.16.0.0 to create 32 subnets?
172.16.0.0 is really a B Class address with 16 network bits and 16 host bits, i.e. Network Address 172.16.0.0 has 255.5255.0.0 as Subnet mask in Classful Addressing. To create 32 (25) subnets we will use first five bits for Network part and will leave 3 bits as Host bits in third octet. Now Addressing will be:Network Address: 172.16.0.0\21 or 172.16.0.0 Subnet Mask: 255.255.248.0First two networks will be : (1) 172.16.0.0-172.16.7.255\21, (2) 172.16.8.0-172.16.15.255\21 and last two networks will be (1) 172.16.240.0-172.16.247.255\21, (2) 172.16.248.0-172.16.255.255\21.(Note to use Zero subnet - remember to use IP SUBNET ZERO command.)
In classful addressing the class of the address can be found by shifting the copy of the address bits to the right?
Shifting to the right won't accomplish anything. To find the class of the address, look at the first octet in the address. You can either look for the range of addresses for a class, or look at the first 3 bits in the first octet: First octetAddress Class0-127Class A128-191Class B192-223Class C224-239Class D240-255Class E 0nnnnnnn. First octet class A range (first bit is 0) 10nnnnnn. First octet class B range (first bits are 10) 110nnnnn. First octet class C range (first bits are 110) It is easiest just to look at the range.
