IPv4 Subnet Cheat Sheet. The IPV4 Subnet Cheat Sheet

Different subnets have different IP allocations and netmasks. Use our IPv4 subnet cheat sheet to see what allocation our subnets have. Customers can purchase additional IPv4 in subnets of /30, /29, /28, /27, 26. The gateway is always your dedicated server IP ending in .254.
