DNS Issue for Client DNS using our DNS as an alias.


hi run web based app customer. clients go buzz.customer.com, set on customer's dns alias app.mycompany.com. forwards traffic customers our public ip , allows them access.

have internal server handles transactions in line web site. noticed time out on connections , have narrowed down error.

nslookup on internal server in question doing nslookup , result:

> buzz.customer.com
server:  dns.mycompany.com
address:  10.1.1.18

non-authoritative answer:
name:    app.mycompany.com
address:  64.84.124.4
aliases:  buzz.customer.com

>

every nslookup following presents:

> buzz.customer.com
server:  dns.mycompany.com
address:  10.1.1.18

non-authoritative answer:
name:    app.mycompany.com
address:  10.1.1.134
aliases:  buzz.customer.com

initial lookup messing internal server , causing not found error, because server needs hit internal address alias of time.

temporarily fixed lookup issue putting entry in hosts file on server in question, think doing more lookups other internal servers in future , not sure want go through trouble of adding host entry every server.

thinking may able add host record in dns server force lookups desired page, there easier way?

thanks!

i agree jorge looking @ forwarders, stub zones, root hints idea.  start clearing client- , server-side cache anywhere have control (eg app server , dns server).  can try query again , if still not accurate, use nslookup query app.mycompany.com against forwarders.  see answer come with.
