You can't have a subnet of 10 ip addresses!
You can have 4, 8, 16, 32, 64, 128, 256, 512, 1024 and so forth
which are /30, /29, /28, /27, /26. /25, and /24
The lowest is the network
Next is the gateway
Highest is the broadcast address
> Default Gateway 65.194.192.1
So your network is probably 65.194.192.0
> IP Address 65.194.192.195
This must be One of your IP addresses (from 0 to 195???)
> Subnet Mask 255.255.240.0
That subnet is for 32 class C networks!!!1
> PTR record 65.194.192.195/20 www.wappoocreek.com
/20 is definitely of A Hell Of A Lot Of ip addresses
I think the information you give is incorrect!!!!
