When you run dig like this, it sends one query to a server, and shows you the response. The dig command does not do recursive resolution. > - Does the titi.be and toto.be be on the same server to correctly use > CNAMES? No. A recursive DNS resolver will be able to follow the CNAME chain from server B back to A to look up records in titi.be.
