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 ?!
