The IP has no reverse name configured: > nslookup 147.67.37.17 ** server can't find 17.37.67.147.in-addr.arpa: SERVFAIL So I'm not sure where the host name from the firewall software is coming from. I tried and got a certificate that looks like it is from the European Commission > curl -v https://147.67.37.17 ... * Server certificate: * subject: C=BE; ST=Brussels-Capital Region; L=Brussels; O=European Commission; CN=*.ec.europa.eu ... It looks like this is a server from the EC and I consider it unlikely that they are using a shared hosting provider.
