Hello again

Thanks for your email Barry! I compiled BIND 4.9.7 on my 4.3.1 AIX and
installed it. But it seems, that BIND 4.9.7 has the same alias-problem as
BIND 4.9.3. The receiver gets the DNS-Answer from the original IP-Adresse
instead from the alias adress! (See the ipreport with BIND 4.9.7 below).
So I think the only way is to convert my files to BIND 8... or has anybody
else an other solution for my problem BIND on alias-IP with AIX?
I'm thankful for every help
Didi


Here is my ipreport:
