New port & Domain database updates?

[Pilli]

I have been using the "New port & Domain database" update feature, just as a matter of interest how often is this updated at DCS?

The port/domain databases are usually updated several times a month. I'd recommend updating once a month (any more is not necessary), but there's no great urgency - just download them whenever you like :)

There's no indication about number of descriptions or latest update date, only telling it's up to date or if we would like to update now.
But updating goes smooth, so no problem.

I always wonder about whois servers/urls if such lists ever need updating too.
I still get from PE the most complete whois results.
