It depends on whether there are streetlights or not.

That may be the strict definition but in practice no streetlamps
and no signs in a built up area is an unlikely combination.
Besides, it is not possible to go wrong to assume a built up area
is 30mph until informed that you are allowed to go faster.

That depends on the country you are in.

What has that got to do with it? In other countries I have visited,
30mph or 50kph seems to be universal unless otherwise informed.
