You need to understand how IP addressing and subnetting works, with a good understanding you will able to configure your network. If you are using a class A addressing the highest number you can use is 184.108.40.206, this link should help
IP Address Subnetting Tutorial IP Address Subnetting Tutorial

136.0.0 would indicate that this range starts at the beginning of the subnet. The fact that it is a /22 would mean that it’s dotted quad (ie. xxx.xxx.xxx.xxx) subnet mask would be 255.255.252.0. So the first ten addresses would be 220.127.116.11 – 18.104.22.168.
Your file/print server could be 22.214.171.124 the next available address and the computer could be 126.96.36.199.
Hope that helps,
Nick is correct, you can use larger than 126 because he is using CIDR, (classless inter-domain routing) where you use the subnet mask to break down into a subnet that does not follow the A, B, C, D class norm.
