Re: Subnet mask
So this value means anything from 216.239.114.0-216.239.114.255 .

Re: Subnet mask
You can use the ipcalc utility to do
various "calculations" related to IP addresses:
$ ipcalc --usage
Usage: ipcalc [-bhmnps?] [-b|--broadcast] [-h|--hostname] [-m|--netmask]
[-n|--network] [-p|--prefix] [-s|--silent] [-?|--help] [--usage]
example netmask:
$ ipcalc -m 216.239.114.0/24
NETMASK=255.255.255.0
accordingly the broadcast address:
$ ipcalc -b 216.239.114.0/24
BROADCAST=216.239.114.255

Re: Subnet mask
11111111.11111111.11111111.00000000
When all octects are 1, the value is 255, when all 0 is 0, a simple binary to decimal conversion.
So, when you say /24, you are saying that you have 24 subnet mask bit to 1, that would be translated to 255.255.255.0, if you say /16, that means 2 octets to 1, giving 255.255.0.0, and /8 would be:
11111111.00000000.00000000.00000000
Or 255.0.0.0.
This is very simple, but this can be more complex if you use a subnet mask like 255.255.252.0. It worth to learn what this does.
