I do bulk lookups on that kind of scale when I am preparing a recursive
server to go into production. I use this small (250 line) program as a
front end to adns that works the way I like. It can easily manage
thousands of queries per second.

(That URL may stop working within the next few months because we're moving
to GitLab and my old git server will be shut down, though I would like to
find somewhere to host redirection tombstones...)

North Foreland to Selsey Bill: Westerly 5 or 6, decreasing 3 or 4,
becoming variable 2 to 4 later. Slight or moderate, becoming slight
later. Showers, occasional rain later. Moderate or good, occasionally
