Point Subdomain to other IP

[DaHaiz]

Hi guys!

i know, usually it should be dead simple to point a subdomain to another ip address just by adding an A-DNS Entry for the subdomain and the other ip.
I've done this several times now and also restarted the whole container, but the changes seem to be not applied really.

the tld (outdoorsportshop.de) points to 178.77.99.229, the subdomain plenty.outdoorsportshop.de should point to another ip.
i've added the following A entry with the dns settings for the subdomain:

plenty.outdoorsportshop.de. IN A 217.24.219.51

the zone file in a whole (without the SOA entry) looks like the follwing snippet:

outdoorsportshop.de. IN NS ns.outdoorsportshop.de.
ns.outdoorsportshop.de. IN A 178.77.99.229
outdoorsportshop.de. IN A 178.77.99.229
webmail.outdoorsportshop.de. IN A 178.77.99.229
mail.outdoorsportshop.de. IN A 178.77.99.229
plenty.outdoorsportshop.de. IN A 217.24.219.51
ftp.outdoorsportshop.de. IN CNAME outdoorsportshop.de.
*.webmail.outdoorsportshop.de. IN CNAME outdoorsportshop.de.
www.outdoorsportshop.de. IN CNAME outdoorsportshop.de.
outdoorsportshop.de. IN MX 10 mail.outdoorsportshop.de.
outdoorsportshop.de. IN TXT "v=spf1 +a +mx -all"


but the A results for the dns queries for the following domains do all point to 178.77.99.229:

plenty.outdoorsportshop.de

nonexistingsubdomain.outdoorsportshop.de
http://www.dnswatch.info/dns/dnsloo...ain.outdoorsportshop.de&type=A&submit=Resolve

outdoorsportshop.de
http://www.dnswatch.info/dns/dnslookup?la=en&host=outdoorsportshop.de&type=A&submit=Resolve


I'm not that familiar with the DNS-System, i hope you can help me!

thanks in advance,
