The subnet cheat sheet
Different subnets have different IP allocations and netmasks. Use our cheat sheet to see what allocation our subnets have. We mostly include a /29 subnet in our VPS and dedicated servers. The gateway is always your dedicated servers IP ending in .254. For virtual servers, the gateway is different for each host node on our network. If you order additional IPs with dedicated servers these will need to be configured inside your dedicated servers networking files. For virtual servers, all you need to do to get your IPs to ping is to log into the virtual server control panel and click the “reconfigure networking” option and our system will automatically change your virtual servers networking files. This also works for IPv6.
