Hello,

Working on a new project that needs to identify ony USA based IP addesses.

I have a list of USA based IP's which I will convert to ranges of Longs.. example (3.0.0.0 - 3.255.255.255 = 218103808 - 22229811)

So I will place this list into memory somehow.

Would like suggestions on how best to find when in ip is in range from a list of about 7000 ranges?

thanks
