see my later message using MX

mail.foo  A       3.4.5.6
www.foo   CNAME   foo

When I look at my DNS records at namecheap I see the record type, host,
value (IP address) and the time-to-live. Re-arranging the above to that
yields

A Record   foo  Web host
MX Record  foo  mail My office
A record   mail.foo  My office
CNAME      www.foo  Web host

But the web host has a diffierent IP address than does my office, so both
couldn't be foo.

Still confused,
