Suppose I have
example.com and the nameserver I'm using is the one from the hosting server where I'm hosting the main site, say
Now suppose I add a new subdomain e.g.
bla.example.com which I'm hosting somewhere else, say at
This typically requires editting the DNS settings at
mainhosting.com, adding an A record for
bla.example.com to resolve to the webserver's IP address at
Is it also possible to set things up so
bla.example.com (but only the subdomain, not the entire
example.com domain) is using
subhosting.org's nameserver instead? So whenever the IP address for
subhosting.org's webserverver changes, it can be updated automatically.
I mean the webhoster at
subhosting.org can typically update any relevant DNS settings for their own webservers automatically, but obviously this doesn't work when I'm using an external nameserver (and thus the DNS records are configured externally).
