Well, I have to say no and no

  1. qr// works fine with \b, e.g. 
    my $string = q/This is a test./;
my $regex1 = qr(\bis);
my $regex2 = qr(is);
print $string =~ /$regex1/g, "\n";
print $string =~ /$regex2/g, "\n";
# prints
is
isis

  2. Your second part
    $ip = qr("192.168.3.5");
    matches e.g. "192 16833!5" but not what was being looked for. Did you maybe want to use the quotemeta function?? Then 
    my $ip = "192.168.3.5";
$ip = quotemeta $ip;

    would be the way to go.
