IIRC DNS uses port 53.
You remember correctly, Jeremy. :)
But, a subtle point...
The DNS requests hit the DNS *server* on port 53. It uses UDP for most requests, but switches to TCP if the answer is expected to be large -- for example, when a domain's zone file is being transferred.
But the port at *your* end can by anything. Like any other outbound request, the operating system will choose any port it likes for the *source* port of the connection. Usually there's a pattern, e.g. it starts at port 1024 when the machine first boots, and subsequent requests go 1025, 1026 etc. But different operating systems have different patterns.
