Insert a new zone

At top menu you have a link to get Back to the previous list and cancel the current process of introducing a new zone. At body you see a register form for forward and/or reverse name (Figure 7.31) resolution zones. You find the following definitions:

1. Domain: Name of the new zone to create; e.g. companyx.com; porto.companyx.com; easylinux.com;
2. Network: The associated IP network for which you are going to create registrations. This is used only for reverse name resolution records (PTR^7.7);
3. Zone type: Field that allows you to create a master or secondary zone. A secondary zone is a copy of another DNS server master zone;
4. Server: Name of the machine that will serve^7.8 this domain (e.g. ipbrick.domain.com) (this field is only applied on master zones);
5. Email: E-mail of the responsible for this domain. This e-mail is registered in the DNS under the name of the administrator for this domain (this field is only applied on master zones);
6. Refresh time: The time of a secondary zone to see if there are any changes in the master zone (this field is only applied on master zones);
7. Transfer retry time: The time a secondary zone has to wait to retry the connection to the master zone, that is, if the last refresh was unsuccessfully (this field is only applied on master zones);
8. Expiry time: The time a secondary zone has to consider the dates of a zone as valid since the last successful refresh (this field is only applied on master zones);
9. Default time-to-live the time in which the other DNS servers have to consider the dates of this zone as valid (this field is only applied on master zones);
10. Master servers: IP address of the master server for that zone (this field is only applied on secondary zones);
11. Visible in the management of machines: If selected, all these definitions will appear too under domain management.

Figure 7.26: Support Services - DNS - Name resolution zones

If the idea is to create a sub-zone these are the necessary steps (Example: porto.companyx.com):

• Insert a new zone at the present main menu. At domain type porto.companyx.com;
• Go to domain management of main zone companyx.com and at Name Servers insert:

      Domain: porto.companyx.com
      Server: ipbrick.domain.com        (no need to change that default field)
  

• Go to domain management of sub-zone and start populating it (machines, alias, MX record...)
