  That is a lot of connections for one web site.  Maybe do a DNS lookup and see if that IP is from here.  Either way that mostly look to be connecting to port 80 so I don't think theres a big deal there, but interesting.   ;  Browsers should not normally keep more than 2 connections open to the same site.But if several sites are run from the same IP address, then they could each have two connections, resulting in many  to the same IP.Perhaps it's something to do with Gamedev's AD system.Remember that HTTP 1.1 allows keep-alive, i.e. TCP connections not actually doing any HTTP request right now.Mark   ;  The page itself is one item, yes. But each item on the page is another item. I suspect your browser isn't using keep-alive (where each connection is recycled), so it creates a new connection for each image on the page.
