I am looking for detailed instructions on how to create DNS records to handle adding www to my subdomains (all domains served to the same IP), blog.foo.com and msv.foo.com.

I’m trying to transfer my public managed DNS provider but I have questions since my current setup is weird. First, My registrar (some small co) provides my domain name registration but no DNS hosting. Only options to specify NS hostnames. My DNS hosting is my ISP, no web portal access to zone file for modification … Read More “Transfer managed DNS provider” »
