The ISP that hosts my personal domain name says that I can't change my CNAME to web.mac.com without "a corresponding A record that defines the IP address of 'web.mac.com'. Please create the A record for 'web.mac.com' first, and you should then be able to update the CNAME record".
Does anyone know what the IP address is for web.mac.com?
