It's not a security thing. We do this with the the resellers who white label our VOIP. CNAMEs allow us to be flexible with our own hosts and infrastructure without having all of our resellers change DNS records.

Subject: CNAME records in place of A records

 

Hi,

Sorry if this is a bit OT. Recently several different vendors (in completely different fields) where they white label for us asked us to remove A records that we have going to them and replace them with CNAME records. Is there anything *going around* in the security aranea  that has caused this?
