...testede lige http://www.sunddebat.com - og det er ikke lykkedes mig at åbne den endnu. Derfor blev jeg lidt nyfiken:
WARNING.
The parent servers (I checked with m.gtld-servers.net.) are not providing glue for all your nameservers. This means that they are supplying the NS records (host.example.com), but not supplying the A records (192.0.2.53), which can cause slightly slower connections, and may cause incompatibilities with some non-RFC-compliant programs. This is perfectly acceptable behavior per the RFCs. This will usually occur if your DNS servers are not in the same TLD as your domain (for example, a DNS server of "ns1.example.org" for the domain "example.com"). In this case, you can speed up the connections slightly by having NS records that are in the same TLD as your domain.
WARNING!
You have duplicate MX records. This means that mailservers may try delivering mail to the same IP more than once. Although technically valid, this is very confusing, and wastes resources. The duplicate MX records are: mail6.servage.net. and mail5.servage.net. both resolve to 77.232.66.114.
WARNING!
Your domain does not have an SPF record. This means that spammers can easily send out E-mail that looks like it came from your domain, which can make your domain look bad (if the recipient thinks you really sent it), and can cost you money (when people complain to you, rather than the spammer). You may want to add an SPF record ASAP, as 01 Oct 2004 was the target date for domains to have SPF records in place (Hotmail, for example, started checking SPF records on 01 Oct 2004).
FAIL!
ERROR: I couldn't find any A records for sunddebat.com. But I did find a referral to www.sunddebat.com. (and maybe others). If you want a website at sunddebat.com (as well as www.sunddebat.com), you will need an A record for sunddebat.com. If you do not want a website at sunddebat.com, you can ignore this error.
...lidt for Steen at tage et nærmere kig på ;)
