voila quelques resultats complementaires....
WARNING: Your nameservers do not include any corresponding A records when asked for your NS records. They probably are not returning the A records when asked, which can prevent some other DNS servers from contacting your DNS servers. The problem record(s) are:
Nameserver 194.5.37.61 did not provide any IPs
Nameserver 194.5.37.65 did not provide any IPs
WARNING: All of your nameservers (listed at the parent nameservers) are in the same Class C (technically, /24) address space, which means that they are probably at the same physical location. Your nameservers should be at geographically dispersed locations. You should not have all of your nameservers at the same location. RFC2182 3.1 goes into more detail about secondary nameserver location.
ERROR: Your nameservers disagree as to which version of your DNS is the latest (2005032901 versus 2005052201). This is OK if you have just made a change recently, and your secondary DNS servers haven't yet received the new information from the master. I will continue the report, assuming that 2005052201 is the correct serial #. The serial numbers reported by each DNS server are:
194.5.37.61: 2005032901
194.5.37.65: 2005052201
ERROR: Your SOA (Start of Authority) record states that your DNS contact E-mail address in hostname format is:
hardware@xelacom.fr.. However, that is NOT valid; it should be: "hardware.xelacom.fr." (without the quotes).
WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). This probably won't cause any harm, but is a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server.
mail.cap-technologies.com claims to be non-existent host ns43.hostfr.net:
220 ns43.hostfr.net ESMTP
