Analysis
Name Servers
rfs.gr carries NS records delegating to ns.second-ns.com, ns3.second-ns.de and ns1.your-server.de.
There is at least partial name server overlap between rfs.gr and other domains — solidncverify.com, 3.e.5.6.a.0.d.0.8.f.4.0.1.0.a.2.ip6.arpa, langcor.net and two more among them.
These name servers are routinely deployed together with the name servers hydrogen.ns.hetzner.com.
ns.second-ns.com, ns3.second-ns.de and ns1.your-server.de are three hostnames that each resolve to a pair of IP addresses: ns.second-ns.com to 213.239.204.242 and 2a01:4f8:0:a101::b:1, ns3.second-ns.de to 193.47.99.4 and 2001:67c:192c::add:b3, and ns1.your-server.de to 213.133.100.102 and 2a01:4f8:0:1::5ddc:1.
