Hi.
I would like to ask You about an idea how to achieve following behavior:
one of the fields in the form is responsible for holding information about DNS server in a particular domain. If the DNS server is in that domain another field for IP address should be added to the form - for example if for domain example.com user enters DNS "ns1.example.com" and submits the form - the validation should return error message with additional input field for ip address of that "ns1.example.com". This additional field should also be run through validation (for valid_ip rule).
Could You give me some hints?
Thank You.
