Stuck on Network Hosts

The Perfect 10.04 Server instructions say to make the etc/hosts file look like this:

Code:

127.0.0.1 localhost.localdomain localhost
192.168.0.100 server1.example.com server1

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

I'm not sure exactly what "look like this" means. Here's mine:

Code:

127.0.0.1 localhost
127.0.1.1 mammy.ec.rr.com mammy

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Do I do this?:

Code:

127.0.0.1 localhost.voodoonet localhost
192.168.0.194 mammy.ec.rr.com mammy

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Mammy is my server, voodoonet is may local network name, I'm on roadrunner so ec.rr.com refers to my time warner ISP

 

Thank you!
