1> Request 2 IP's from your provider (DONE)
2> Go to your registrar and register the nameservers.
Example:
ns1.mynameserver.com 216.**.***.**1
ns2.mynameserver.com 216.**.***.**2
3> Add A records for your nameserver
mynameserver.com NS ns1.mynameserver.com
mynameserver.com NS ns2. mynameserver.com
ns1.mynameserver.com A 216.**.***.**1
ns2.mynameserver.com A 216.**.***.**2
mynameserver.com A 216.**.***.**3
webmail.mynameserver.com A 216.**.***.**3
ftp.mynameserver.com A 216.40.***.**3
mail. mynameserver.com A 216.**.***.**3
www. mynameserver.com CNAME mynameserver.com
mynameserver.com MX 10 mail.mynameserver.com
216.40.***.**3/24 PTR mynameserver.com
4> DNS Templete
<domain> NS ns1.mynameserver.com
<domain> NS ns2.mynameserver.com
<domain> A <ip>
webmail.<domain> A <ip>
ftp.<domain> A <domain>
mail.<domain> A <domain>
<domain>. MX 10 mail. <domain>.
<ip>/24 PTR <domain>
**<<Note the www CNAME is automatically added by Plesk>>
It is best to set the templete up before you add sites to your server, because then your dns for all sites will automatically have the correct settings for your nameservers.
