Search Again: Re: Missing A records and slow resolution From: Aaron Lynch Date: Monday, December 13, 1999 Time: 4:27:00 am Personall, I've found cnames so problematic, that I just don't use them at all. AFAIK it's perfectly ok to use multiple A records for a host, so the way I see it, if a client requests a host which is a cname then it has to also find out about where the c name points. so in the best case, if everything works perfectly, a cname doubles the load on the server. I just don't get why you'd wanna do this : ) my suggestion is to make then all a records, unless somebody else might have a compelling reason not to do this.
