Try http://www.hostip.info it is reasonable accurate in most cases and
hell it is for free. It depends what you need it for of course but it is
far better than nothing.

64.29.76.9, your mauigateway.com pops up correctly as Honolulu.
205.166.249.10 is guessed to be somewhere random in the US.

The problem with this one is that they are still gathering data and they
depend on user input, but it looks pretty accurate to what I have found
out.

Most of these kind of databases rely on user input though. I am quite
sure that Google, using their search thing and especially Orkut has
quite some info on this. Shopping Sites like Ebay and Amazon of course
get their shipping info for free and thus can pretty much pinpoint the
city correctly after $x percentage of customers bought from there.
Problem in the end is of course when there is a huge pool and the
end-users change a lot, but then the country is accurate enough already.
