I have to convert 2 DWORDs, IP address and a network mask to CDIR format…
So I have 2 DWORDs corresponding 1.1.1.1 and 255.255.255.255 and I want to come up with string
1.1.1.1/32
Any thoughts on this?
Thanks
Since there are a small and fixed number of valid netmasks (32, to be exact), the fastest way is probably to just build a map of masks to prefix length once at init time, and the conversion is just a lookup in the map.
