cURL, using IP's Vs Domains. Fastest?

[daydreamer]

I am using cURL to visit/download pages on my server.

 

I was just thinking about the most effective and fastest way to write my code.

 

Wouldn't it be quicker to write:

 

curl_setopt($curl, CURLOPT_URL, 'http://66.102.9.99');

 

than:

curl_setopt($curl, CURLOPT_URL, 'http://www.google.co.uk');

 

because cURL wont have to go to a DNS and resolve google.co.uk to 66.102.9.99?

I'd use the domain name because just in case a site changes IPs, you wouldn't need to go around fixing everything.  DNS isn't that slow.

true, but it would still be faster even if by only milliseconds wouldn't it?

 

Dont major websites have static IP's though because its better for search engine optimization?

I mean, most sites have static IPs, but you never know.  What does the millisecond difference matter?  I don't even think you'd be able to measure the speed change accurately. >_>

just for that little bit extra performance.

There's MUCH better places to focus your optimization goals on.  I'd suggest making sure everything else is completely optimal before you worry about DNS.
