"ip domain-lookup" is a double-edged sword: with it, you get helpful DNS resolution. However, your typos also then hang on a response. One surprising area where it's notable is in certain command output - for instance, "show ip mroute" does not do any resolution, but "show ip mroute active" does. "show ip bgp sum" does not, but "show ip msdp peers" does.
Moral of the story? If you're going to have domain resolution, be thorough about it, because if you don't your exec sessions take a long time to respond.
