what do you consider a "German server"?

- a server with a German ip address according to the ripe db
- a server physically located in Germany
- a server with an ip address reverse resolving to a .de domain
- a server operated by a German individual


Recently I dumped my own dns cache into a perl script and compared the
ip addresses stored with those from an open danish dns server poisoned
with the danish dns blocklist. I found a lot of blocked servers within
the Chinese tld .cn using ip address space from the US.
