Hello I have a client's vendor that (since the whole domain cannot be moved) wants to delegate the management (adding and removing records) of a subdomain to our client in ISPConfig. Let's say this subdomain is subdomain.domain.tld . Vendors nameservers are ns1.domain.tld and ns2.domain.tld . We have a fairly standard ISPConfig setup with a web server and two name servers, ns1.ourdomain.tld and ns2.ourdomain.tld . Subdomain delegation is not something I've configured before but after some googling it seems pretty straightforward. First we should create a zone for subdomain.domain.tld in ISPConfig and add all the necessary A, MX, TXT, DKIM etc. records. Then the vendor should remove all other records for subdomain.domain.tld in their domain.tld zone file and only have NS records pointing to our nameservers, like so: subdomain.domain.tld IN NS ns1.ourdomain.tld subdomain.domain.tld IN NS ns2.ourdomain.tld And that's it. With those records in place all the queries for subdomain.domain.tld should be forwarded to our nameservers. Is this correct? Is there anything ISPConfig specific that I'm missing or would this setup work? Thank you for your time.
I think that is about right though it is not really safe for your client in practise since the subdomain is not really his or under his total control in real sense.
