Hello everyone,

I have the following regular expression:
/[A-Z0-9]+[A-Z0-9-]+[A-Z0-9]{1}/i
but it doesn't appear to work. (It is supposed to match one part of a domain name)

I've tried testing with: 

#!/usr/bin/perl -w
#

my $domain = $ARGV[0];
print "Got $domain\n";

if ($domain =~ /[A-Z0-9]+[A-Z0-9-]+[A-Z0-9]{1}/i)
{
        print "$domain matched\n\n";
}
else
{
        print "$domain did not match\n\n";
}

but then it doesn't seem to match properly: 
[~/code/perl] ./match.pl someRandomName.
Got someRandomName.
someRandomName. matched

[~/code/perl] ./match.pl someRandomName-
Got someRandomName-
someRandomName- matched

Can someone tell me why it is matching the . or the - at the end of the line?
