Why is this happening?

The Rootserver returns a wrong entry I fixed containing 5269.XXX.com. instead of 5269 XXX.com.

Wait for the DNS entries to propagate. It depends on your TTL that you set for the record.

Hi malfy... indeed, but that still doesn't explain why different results are returned. –  Henrik P. Hessel Dec 28 '10 at 3:35
    
Maybe one of the hosts is caching the DNS entry? That is all I can think of at the moment. Give a bit more detail on how you are testing these records, Macbook@Home, and you tested it again from that same Macbook? –  atx Dec 28 '10 at 4:00

Seems that I'm using the Google DNS in Frankfurt and the Rootserver the Google DNS in Berlin
