CNAME note

Question

Good afternoon,

Maybe it is a very basic question, but I am not very familiar with DNS and I need to clarify a question so as not to waste time with propagation. Come on:

I have two domains hosted in two different locations, let’s say one on Locaweb and the other on Uolhost. Let’s call domains X and Y, respectively. The goal is that when my client accesses the www.dominioX.com.br address (which is already widely publicized) he will fall on my site www.dominioY.com.br.

Then I thought of pointing WWW.dominioX.com.br to WWW.dominioY.com.br. Whereas both are staying in different locations, could I create a CNAME record in the domain by pointing the WWW name to WWW.domainyY.com.br ? That would be the right way?

Note: My domain.com.br hosts web applications from various clients, for example: clientA.dominioX.com.br, clienteB.dominioX.com.br ...

Answer 1

If I understand well inside your X domain you have several sub-domains for your customers, right? Then you need to redirect your X domain to the Y domain address and you may have to do the same for the subdominiosX(clienteA.dominioX.com.br, clienteB.dominioX.com.br...).

If you can create a Cname for the domain X where Voce can inform the IP of the server where the domain Y is, it will probably work. But I don’t think you will have this option. In the case of Domain Name Cname works because they are on the same server. The simplest and fastest is to redirect.
