You need to add A records (or CNAME records) to your DNS zone pukruppa.net: one.pukruppa.net. A 213.146.114.24 two.pukruppa.net. A 213.146.114.24 ... Or, alternatively, use CNAME (don't forget the trailing dots) pukruppa.net. A 213.146.114.24 one.pukruppa.net. CNAME pukruppa.net. two.pukruppa.net. CNAME pukruppa.net. ... Setting A records directly saves one additional lookup though. You could also use Wildcard DNS records (*.pukruppa.net. A ....), but I wouldn't recommend this. BTW, you could also use a better PTR record for your IP: 24.114.146.213.IN-ADDR.ARPA domain name pointer reverse-213-146-114-24.dialin.kamp-dsl.de kamp-dsl will be glad to set up a reverse record for you if you asked them. -- Cordula's Web. http://www.cordula.ws/
