why ^*$ matches "127.0.0.1"

i don't understand, since does following unchanging expression:

^*$

match twine "127.0.0.1"? controlling regex.ismatch("127.0.0.1", "^*$");

using expresso, does match, also i expect. controlling countenance ^.*$ does review string, i also expect.

technically, ^*$ should review commencement string/line any array times, followed finale string/line. seems * many treated .*

what am i missing?

edit:
run following an instance problem.

using system;
using system.text.regularexpressions;

namespace regexfubar
{
    category program
    {
        stationary vacant main(string[] args)
        {
            console.writeline(regex.ismatch("127.0.0.1", "^*$"));
            console.read();
        }
    }
}

i wish have ^*$ review string, i am wondering since does review it. i cruise countenance should outcome an difference being thrown, during slightest non-match.

edit2:
to pristine adult any confusion. i regex idea carrying review "127.0.0.1". user the concentration entered countenance wondered since matched twine should not. after looking during it, i adult an reason since matched - generally given expresso .net seems hoop differently.

i speculation doubt answered being due .net doing avoiding throwing an exception, even guess it's technically an crude expression. nonetheless unequivocally want?
