What subnet mask or CIDR notation would be required to maximize the host counts while still meeting the following requirements: 192.168.228.0 255.255.255.128 Required Networks: 2 Required Hosts: 20

192.168.228.0 255.255.255.224

Explanation:

192.168.228.0 255.255.255.128

subnet mask: defines the host and the network part of a ip

CIDR notation : is the shortened form for subnet mask that uses the number of host bits for defining the host and the network part of a ip

For example: 192.168.228.0 255.255.255.128 has CIDR equivalent of 192.168.228.0\25

To have atleast 20 hosts

20 ≤ (2^x) -2

x ≈5

with 5 host bits, we have 2^5-2 = 30 hosts per subnet

and 2^3 = 8 subnets

To get the subnet mask, we have 3 network bits

1110000 to base 10 = 2^7 + 2^6 +2^5= 224

192.168.228.0 255.255.255.224

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
