What is the expected time between port scan for an arbitrary IPv4 address? Is the level of scanning activity so high (or so well-targeted to "promising" address spaces) that one should expect to be scanned in minutes?

- Symbiote 10y agoI have between 2500 and 40,000 SSH login attempts on a server on my home broadband in Denmark, usually around 30,000. That's one every 90 seconds or so. Wow. I don't know about other ports, other than HTTP I don't have any open. A server on slow home broadband in the UK is only receiving 100-300 attempts per day. It's almost identical to the one in Denmark, except the broadband is terrible. Several servers in a university's IP space has about 5000-10000 attempts per day.
