Generally speaking, we required countless subnets. For this reason, an IP network required that has more has pieces to acquire from. For instance, the class B network address 184.108.40.206 has a default veil of 255.255.0.0 or/16 Prefix. Along these lines, this address has 16 organization bits in the organization part and 16 host bits in the host segment. The 16 pieces in the host segment are accessible to get for making subnets.
The table in the figure beneath features every one of the potential situations for subnetting a/16 prefix. The complete number of the host in an organization with/16 prefix is ( 216-2 =65536 ). This is an enormous organization, for better administration and execution we can subnet this organization as indicated by our necessity. The table in the figure beneath features every one of the potential situations for subnetting a/16 prefix.
Model – You are an organization head for an enormous undertaking that requires 60 sub-organizations. You have the Public location 220.127.116.11/16.
Acquiring pieces from the above notice/16 prefix organization, it should begin in the third octet, going from left to right. Acquire a solitary piece individually until the estimation scopes to 60. You can likewise counsel the table in the above figure which shows the quantity of subnets and furthermore the quantity of host per subnet. We can likewise make a custom table for 60 subnets. The table underneath shows the quantity of subnets that can be made while getting pieces from the third octet. Notice there is up to 14 host bits that can be acquired in the Class B organization.
IP Address – 18.104.22.168
Subnet Mask – 255.255.0.0 of/16
Network Bits (N) – 16
Have Bits (H) – 16
Required Sub-organizations – 60
For 60 Sub-organization, we have expected to acquire 6 pieces from the third octet. The prefix will be changed for each organization from/16 + 6 =/22. The subnet cover will be 255.255.252.0 for each Sub-organization and all out with 6 acquired pieces we can make 64 subnets. For Network ID we will follow the accompanying method.
There are 6 acquired pieces. The course of action of these acquired pieces will be as indicated by the organization number like the accompanying table.
|Network Number||Borrowed bits arrangement in the third octet||Remarks|
|0||00000000||The first six digits are the binary of the 0|
|1||00000100||The first six digits are the binary of the 1|
|2||00001000||The first six digits are the binary of the 2|
|3||00001100||The first six digits are the binary of the 3|
