The next step is the Reverse Zone for our virtual zone

Adding the Reverse Zone

  1. Click on create new master zone
  2. This time the zone type is: Reverse
  3. Domain name / network:
  4. Records file: Automatic
  5. Master server:
  6. Email address:
  7. Use zone template: no
  8. Refresh time: leave as default
  9. Expiry time: leave as default
  10. IP address for template records: leave as blank
  11. Transfer retry time: leave as default
  12. Default time-to-leave: leave as default
  13. Click create

Edit master Zone

  • Create Pointer/ Reverse address record
    1. Click on PT
    2. Add the address: (complete IP)
    3. Time-To-Leave: Default
    4. Host Name:
    5. Update Forward?: yes
    6. Click on create
      Entering IP
      Fig 9.31 This is the Ip for the virtual domain
    7. Return to record type

    Adding the Name Server (NS)

    (This record may be already updated)
    1. Click on Name server
    2. Zone Name:
    3. Time-To-Leave: Default
    4. Name Server:
    5. Click on create
      Adding Record
      Fig 9.32 This is the Ip for the virtual domain
    6. Return to record types

    Add Name Alias Record (CNAME)

    1. Name: www
    2. Time-To-Leave: Default
    3. Real Name:
    4. Click on create
    1. Name: mail
    2. Time-To-Leave: Default
    3. Real name:
    4. Click on create
    1. Name: ftp
    2. Time-To-Leave: Default
    3. Real Name:
    4. Click on create
      Fig 9.33 These are the aliases for the virtual domain
    5. Return to zone list
    Click on apply changes. And we are done, it should be working.

    We just created the entry into the DNS server; however, we still have a couple of steps to go. If you do an nslookup, it will not respond. Next we need to bind the IP address to the interface card and make it active in order to be used.
