A long while ago, I wrote about the brokenness of socket API and lack of session layer in TCP/IP stack.

It looks like I’m not the only one with heretic opinions; Fred Baker reached similar conclusions in his Happier Eyeballs draft and Brian Carpenter recently published a lengthy article title IP Addresses Considered Harmful which documents (among other things) the history of socket API and the reasons DNS isn’t tightly integrated with it. Both documents are definitely worth reading.
