<double> RegEx catching IP addresses

I'm using a parser, which mistakenly parses IP addresses as double values. Since I know nothing about regular expressions, take a look:

AddRule<double>("!!float", @"[-+]?(0|[1-9][0-9_]*)\.[0-9_]*([eE][-+]?[0-9]+)?",
            m => Convert.ToDouble(m.Value.Replace("_", "")), null);
AddRule<double>("!!float", @"[-+]?\._*[0-9][0-9_]*([eE][-+]?[0-9]+)?",
            m => Convert.ToDouble(m.Value.Replace("_", "")), null);
AddRule<double>("!!float", @"[-+]?(0|[1-9][0-9_]*)([eE][-+]?[0-9]+)",
            m => Convert.ToDouble(m.Value.Replace("_", "")), null);

Is there some quick way to fix that? (The error is on the first lambda expression)

Alright, this does the trick.

AddRule<double>("!!float", @"^[0-9]*(?:\.[0-9]*)?$",
            m => Convert.ToDouble(m.Value.Replace("_", "")), null);
