Network IP Can one network have multiple hosts?

Question

Hello,
I'm wondering if it's possible for one network address to have multiple hosts, each of which is assigned to a different company. For example:

Say I have the following IP Addresses
132.222.231.51
132.222.231.19
132.222.231.22
132.222.231.38

Would all of these belong to the same server/company, or can each one of these actually be a separate/independent entity on the web?

Thanks,
R

Answer 1

You can separate them completely by subnetting.



For example, instead of your standard 255.255.255.0 class C subnet. You could logically separate the addresses and keep ranges independent from other servers or broaden it.



so 255.255.255.224 would give you usable addresses:



132.222.231.1 - 132.222.231.30 (.0 is your network address, .31 is broadcast) This would logically separate the first two addresses of 132.222.231.22 and 132.222.231.19.



The next usable range would begin with 132.222.231.33 and so on. Just count each increment. This would cover 132.222.231.38 and 132.222.231.51.



So all four addresses are logically separated by 2 networks.



YES. In your scenario, two servers could belong to company A, and the other 2 servers would belong to company B with complete separation unless there is a route to each independent network on the router.

Answer 2

IP addresses are divided up into classes. The class determines how many IP addresses you can put into one network block. In a typical class C network, the normal number of addresses is 256. You can divide larger network blocks down into smaller networks called subnets. This is done to make address available or to isolate parts of a larger network from one another.



To answer your question, the top-level network in question (132.0.0.0) can have over 16 thousand addresses. It's likely that the owner of this network has it subnetted, but the addresses you listed do belong to the name network.



As far as separate, the chances are that these four hosts belong to the same network entity. It's possible that one or two of these could fall in different networks if they were subnetted, but in all likelihood, they're on the same network.

Answer 3

Most larger corporations will buy a subnet which would be 132.222.231.x

so yes all those ips could belong to the same company, but it really depends on the ISP. The ips you posted could belong to a number of different businesses who were assigned that ip range from the ISP.

Most businesses will have a larger subnet to utilize addressing for multiple servers/hosts or departments.

Answer 4

It depends upon the subnet mask which you have not provided.



With the information provided the answer to your question is a very firm "maybe".
