Are there somewhat reputable service providers for Internet-wide TCP
port scans? What's the typical rate per TCP port? (I'm interested in
rather obscure services whose identification may need additional
probing, and this data is unlikely on file already.)
A full scan needs just 0.5 TB of data per TCP port, so "roll your own"
is definitely an option. But I expect that any halfway decent hosting
provider will start asking questions after the first billion packets
or so, and at least over here, broadband access without abuse
management lacks sufficient upload bandwidth, making the results
difficult to interpret because the measurements would span several
days.
