DNS: Dial Access
Help in setting up the zone files to do your own primary name service for your LAN-Dial or LAN-ISDN account can be accomplished by following these steps.
The named.hosts is the zone file for your local domain. Below is a sample template for your domain named.hosts file with your DNS-HOST as the primary name server, and our secondary name servers as secondary.
- Replace all instances of YOUR-DOMAIN with your registered domain name.
- Replace all instances of DNS-HOST with the name of the machine you are installing these files on.
- Replace all instances of MAIL-HOST with the name of the machine that receives mail at your site. The MX records directing mail to the machines mx.smtp.psi.net, mx2, and mx3 are backup mail exchangers to hold your mail while you are not connected.
- Replace HOST2, HOST3, ... and AAA.BBB.CCC.DDD with the actual host names and IP addresses of the machines on your network, respectively.

The named.rev is the zone file for reverse lookups of your local network. Below is a sample template for YOUR-DOMAIN's named.rev file.
- Replace all instances of YOUR-DOMAIN with your registered domain name.
- Replace all instances of DNS-HOST with the name of the machine you are installing these files on.
- Replace DD1, DD2, ... with the last octet of the corresponding host's IP address.
- Replace HOST2, HOST3, ... with the actual machine names.
Please note:
- The expire time on the SOA record should fall between 86400 (1 day) and 604800 (1 week).
- The ttl on the SOA record should at least be 86400 (1 day).
- The primary name server should be configured to allow our secondary name servers to perform zone transfers from it. These servers are:
- sec1.dns.psi.net 38.8.92.2
- sec2.dns.psi.net 38.8.93.2
- Once you have set up the DNS files on your primary name server according to the above prescriptions, send an e-mail to hostinfo@psi.com with the following information:
- Hostname and IP address of your primary name server.
- The domains you wish to host.
Our DNS specialists will verify their ability to perform zone transfers and check the integrity of the zone files on your server. Once this has been done, the reverse delegation will be made and a change template will be sent to the registrar of the domain name(s) to list your primary name server and our secondary name servers.
