    DNS issues with different servers

    There is a domain.com whose DNS is:

    ns1.isp.com
    ns2.isp.com

    ns1.isp.com , ns2.isp.com has:

    domain.com A record pointing to SHARED IP: 195.0.0.2

    www A record pointing to SHARED IP: 195.0.0.2

    On the reciver server side, Apache HTTP is setup properly with ServerAlias for www.domain.com domain.com

    However, we are only able to access the site using

    domain.com

    It does not work using www.domain.com (times out).

    I checked the DNS A records with Dnsreport.com and it confirmed it is A pointing to 195.0.0.2

    I'm thinking maybe www A record should be changed to CNAME record ?

    The ISP dns is running on Solaris 8 , the HTTP server is running FreeBSD 4.x

    Any suggestions ? Have anyone seen problem like that.

    I know from windows if I point www to shared IP, it works fine. but maybe Solaris has a different requirements ?!

    You mention that you already have and 'A' record thus:

    Code:
    www     14400   IN      A       195.0.0.2
    That should be correct.

    I have seen problems like this occur when there's a separate DNS record set up for both the domain.com name and the www.domain.com. There should only be a DNS record set up for domain.com.

    Have a look in /etc/namedb (assuming your FreeBSD is configured the same as mine) and check that there's a file for domain.com.db but not one for www.domain.com.db.

    What times out, the query or the connection to the web server?

    try host/nslookup www.domain.com on your os of choice. if that works, then its not a DNS problem, its an apache problem.
