Subnetting chart6/11/2023 ![]() For example, if you wanted 2 subnets, you had to figure the number you wanted plus 2 – calculate like you wanted 4, i.e. Note: In Windows NT 4.0 you had to subtract 2 from the total number of available subnets. Only in Class C networks does the N value remain the same. In a Class B network instead of saying 5 (for example again, duh!) you must say 5+8. Therefore in a Class A network instead of saying 7 (for example) you must say 7+8+8. N=Number of Non-masked bits – Remember that in Class A and B networks you have other octets besides the one you’re subnetting. The table deals with Subnetting of only one octet. Use this table to help you calculate Subnet Masks, available hosts per subnet or number of subnets per class.
