Greetings, I have a question....
I am planning to restructure my internal domain to be a subdomain of my external root domain (int.jcghome.com which would be internal to jcghome.com). Research, and Microsoft, recommend this over separate domains, though that's also an option I am considering.
This is for a simple home network, with a dynamic IP address. I use TZO as my dynamic DNS provider, and by default they enable wildcard domain lookups (*.jcghome.com). Therefore, my internal subdomain, int.jcghome.com, would be routable to the internet (int.jcghome.com = www.jcghome.com
). Based on the recommendations from Microsoft and elsewhere, having an internal domain match anything routable externally is recommended against.. otherwise there's no need for the subdomain.
So, is having an internal subdomain which is externally routable of concern? For this scenario, would the experts recommend I use a different TLD internally instead of a subdomain?
