MAC vendor lookup

Apparently there is some rate limiting on place now, sleep a bit between requests.

use HTTP::UserAgent;
 
my $ua = HTTP::UserAgent.new;
 
$ua.timeout = 10; # seconds
 
my $server = 'http://api.macvendors.com/';
 
sub lookup ($mac) {
    my $response = $ua.get: "$server+$mac";
    sleep 1;
    return $response.is-success ?? $response.content !! 'N/A';
 
    CATCH {             # Normally you would report some information about what
        default { Nil } # went wrong, but the task specifies to ignore errors.
    }
}
