The IP address given was a class B address, making the first 16 subnet bits static. Using the cheat sheet, find the exponent of 2 that is equal to or greater than the number of subnets we require (900).

Default subnet masks. IP Addresses are divided in classes and the following subnet masks are the defaults for the classes A-B-C: Class A: 255.0.0.0; Class B: 255.255.0.0 ok i been going through subnetting and when it comes to class B subnetting i get confused. I am stuck at 2 problems and here they are. If can help me out, Problem 1:- 172.16.0.0 = Network address 255.255.255.128 = Subnet mask in other words 172.16.0.0 / 25 Problem 2:- 172.16.0.0 = network address Subnet Mask Cheat Sheet. Contents. Table 1-1 represents traditional subnetting of a Class B network address. Subnet Mask # of nets Net. Addr. Host Addr Range

For example, a Class A address has a default subnet mask of 255.0.0.0, a Class B address has a default subnet mask of 255.255.0.0, and a Class C address has a default subnet mask of 255.255.255.0. Looking at the subnet masks, any octet that has the value of 255 means that the corresponding octet in the IP address is part of the network ID.

Boson TCP/IP Cheat Sheet www.boson.com 5 Table 0 Class B Maximum Number of Subnets Calculation for Host ID Maximum Number of Hosts Per Subnet Subnet Mask Subnet Bits Required Host Bits Available Range 0 2 6 – 2 65,534 255.255.0.0 8 6 Class A Range 7/7 & Begin Class B 2 5 – 2 Invalid 28 = Subnet 0 9 5 Not Recommended Dec 12, 2018 · But any mask, whatever it is, is needed in order to hide something or help in something. The default subnet mask for class b is designed to perform the same functions. Application default subnet mask for class b. To use the default subnet mask for class b you need to use the instruction or contact the professionals. The instruction is attached subnet mask wildcard 255 1111 1111 0 0000 0000 254 1111 1110 1 0000 0001 252 1111 1100 3 0000 0011 248 1111 1000 7 0000 0111 240 1111 0000 15 0000 1111 224 1110 0000 31 0001 1111 192 1100 0000 63 0011 1111 128 1000 0000 127 0111 1111 0 0000 0000 255 1111 1111 ip address classes a 0.0.0.0 – 127.255.255.255 b 128.0.0.0 – 191.255.255.255 The other option is to use the cheat sheet, find the subnet mask 255.255.255.252 for the class B address and determine immediately that there are only two valid hosts. Therefore, the first must be 1722.23.236.101. The third question is where the cheat sheet is really useful. Simply consult the table and look for a mask that meets the requirements.
