Hello,
  From looking on the web

 http://marc.theaimsgroup.com/?l=bind-users&m=102608783204875&w=2 
 
 it appears to be ok to have multiple  
 A records for a IP addy ,But it looks like the common method
 of DNS setup for name-based virt web hosts is to use CNAME.

#############################################################
  i.e.
  second_domain.com CNAME first_domain.bz

  or
  
  second_domain.com  A   1.2.3.4

 where 1.2.3.4 is also the IP of first_domain.bz and
 first_domain.bz is the primary domain hosting all others.

#############################################################

Are there pros or cons to either way as far as HTTP and SMTP
are concerned.

 thanks,
 jd
