How can I forward a 'non-existant' subdomain to a 'physical' subdomain? I.e.: api.website.com -> api.company.comWhere the first is just a CNAME pointer and the last is a real subdomain with a root.At website.com I have:api CNAME api.company.com.At company.com I have:api.website.com CNAME api.company.com (also tried this with just API)api.company.com A 1.2.3.4
Forward a 'non-existant' subdomain to a 'physical' subdomain
dns;subdomain
It appears that you want to create a subdomain to a root IP address, and then forward a subdomain from a different domain to this subdomain.First you would create an A record for the api.company.com subdomain as demonstrated here under Example 1 (ignoring the FTP part; also note that www is considered a subdomain as well, just like api). So in the DNS tables for company.com you'd create an A record for:api.company.com A 1.2.3.4This establishes an alias record for host api.company.com at IP address 1.2.3.4Next you'd create a CNAME to this external host as demonstrated here under Example 3. So in the DNS tables for website.com you'd create a CNAME record for:api CNAME api.company.com.This points api.website.com -> api.company.comThen you'd need to wait 24-48 hours for these DNS changes to propagate to DNS servers throughout the Internet in order for these subdomains to resolve properly, so don't make any other changes during that time.
