How to Manage DNS?

Hello

I have a blog on blogger with custom domain that i was bought from xtraorbit.I was add the CNAME And A records for using my custom domain for blogger and it works perfect.

But now the problem is begin for me when i was think to create a sub domain and make it a forum etc for my blog but as you know blogger is not a hosting.

I need to know how can i setup my domain DNS to work with blogger and other web hosting blog works on blogger and forum etc works on hosting server and then i will make a sub domain from the web hosting cpanel.

Please solve me issue thanks for your support!

where do you have your domain name registered??
if its GoDaddy, then use GD's name servers, you'll by then have GD's "Total DNS Management" over your domain, go ahead and point your www or whatever to blogger, create a sub domain and point it to another server and so on, Dynadot have had the same thing is you'd use their own name servers too, DomainSite would let you do it for an extra $1 per year or so, so is Moniker as well (if I remember well), go ahead and try it yourself, shoot me a PM if you can't afford to do it and I'll help you
