I am about to add a new block of IPs to my server using the IP manager and i am a little confused about how to determine the Subnetmask for the range of IPs i was given.
Is there an easy way to calculate the right subnetmask for an IP..?
i tried this site an it tells me the subnetmask:
http://www.subnetmask.info/
But if i look to its results and compare to other subnetmasks and IPs already working in my server, the values dont match..
For example:
i had this set of IP working in my server fine:
64.247.**.** -> subnet: 255.255.255.0
but the site tells me subnetmask should be:
255.0.0.0
Any help?
