some info i collected from RIPE database (the european ip number authority)
IP ranges
ripe is all about keeping track of ip address ranges, so tried those first – ripe database website has a searchtext (though it doesnt goes to search very deep, so it's difficult to get a full overview of things)

notice this IPv4 range is 'assigned PA' : https://www.ripe.net/publications/docs/ripe-733 which is an important detail for the operation of a shared datacenter, as neutrinet cannot specify an abuse-contact to a specific ip address (or range of ip-addresses)

reverse dns lookup
RIPE maintains the .arpa DNS domain to allow for reverse dns lookups;

some notes
RIPE checks dns server ip's
https://www.ripe.net/manage-ips-and-asns/db/support/configuring-reverse-dns
configure your DNS servers in such a way that you will pass all the tests that we will perform. Here are some recommendations to help you:
- Make sure you set up at least two name servers that are authoritative for the zone
- Ensure that the servers are at least in different subnets, but preferably in different networks that are geographically distributed
reverse lookup still lists wannes as contact;
don't know if WDS20-RIPE still reads his emails ? 
WDS20-RIPE is still used; but changing reverse ip info needs second nameserver up & running (in a different subnet..)
