If I have an internal network using 200.200.200.0 255.255.255.0 (which I do not own) and I now need to connect to the Internet and use the alias command to fix the DNS resolution to the outside address of 200.200.200.0 what would the syntax of the alias command be?  I have seen two examples of this, one on the Cisco web site and one in a book and they do not agree on the syntax.  I am using 201.201.201.0 as the alternate address for this example translation.  It is my understanding that the first address is the address being used as the alternate, but because I see two conflicting examples I'm not sure.

Thanks for your help.

alias (inside) 200.200.200.0 201.201.201.0 255.255.255.0

or

alias (inside) 202.201.201.0 200.200.200.0 255.255.255.0

alias [(if_name)] dnat_ip foreign_ip [netmask]


translastion:
alias(inside)<realip> <globalip> 255.255.255.255

So in your case:
alias(inside)201.201.201.0 200.200.200.0 255.255.255.0
