Why would a network mask be set to 255.255.255.10 instead of 255.255.255.0?

I have the following being set up on a laptop automatically when connecting to the wireless router:

IP Address 192.168.0.100
Gateway/Router 192.168.0.1
Network Mask 255.255.255.10

What does this particular network mask value do? I usually see the network mask set to 255.255.255.0. What reason would there be for the network mask to be set to this value?

Your network mask or 'subnet' mask is an allocation by your system within the default range. The default allocation range of subnet masks is 255.255.255.0 - 255.255.255.10.

The reason you may usually have seen it as 255.255.255.0 is because it is the start of the default range, and so is most commonly used by magazines etc because people recognise it. Don't worry though, your allocation is fine.

As for the reason it is set to '.10 can be contributed to several factors, and without seeing your system and network configuration I can't tell you exactly which factor it is. It might be due to a wireless security protocol, but i'm not really sure.
