cURL question...IP address ok?

[wrgill999]

Does usind the cURL functions such as curl_setopt($curl, CURLOPT_URL,'http://70.84.61.2:8100/3rdparty/confirmation.aspx');
require a valid domain name?

Bascially, the above example will not connect. Does it need a valid domain name rather than an IP address, or does the port need to handled differently?

Thanks.

I don't see why it would need a domain name, since all it does with the domain name is grab the nearest DNS server and scream "GIMME IP!" though I could be wrong.
