Hi folks,

How can i calculate the subnet for IP - 10.113.36.46 ?

Hi,

It depends on how many addresses you want to have in the subnet.

is  10.113.36.46 included in 10.108.0.0/16 ?

[Niklas Peterson]

No, 10.108.0.0/16 would contain the IP addresses between 10.108.0.1 - 10.108.255.254.

Use the link provided by @Robbie earlier and you can try different sizes and see the result.

Hi @Community Alums,

As @Niklas Peterson has pointed out and eluded to, to subnet a network is to create logical divisions of the network. Subnetting, therefore, involves dividing the network into smaller portions called subnets.

This is a decision point for you, or more accurately something to clarify with your networking department if you are unsure.

We can't advise, your networking department can and then you can use that link I provided.

Check this link which nicely describes what a subnet is (I've borrowed some verbage above) to help explain.

Does this make sense? Please let me know if I can help any further? Happy to where I can.

Hi,

What kind of information are you looking for? 10.113.36.46 is just the address to a single host. It can be part of a large subnet, a small subnet or a subnet just covering that single address.
