Hi,
I'm testing the DDNS procedure from Infoblox DHCP and MS DNS servers.
At the moment I want to test only one network with no security option.
I want the Infoblox will be able to create/modify both A record and PTR.
Then, from my understanding I have to perform these steps:
1) With client defualt option 12 (hostname)
- From DHCP network "Enable DDNS update"
- From DHCP network I had to specify the domain (option 15) in order to build the FQDN with hostname sent by client
- From configure DDNS (DDNS options) I'll configure the DNS UPDATES TO EXTERNAL ZONES with the forward-zone I want to update.
- FIRST Question : because I want to modify also the ptr record, Should I also add the reverse-mapping zone?
if yes, is this the right format (example of /16 Network): 142.10.in-addr.arpa ?
- Last think I had to do is modify the MS DNS in order to accept update from the member where the netowrk is in charge
2) With FQDN option 81
- Clients must to sand DHCPDISCOVERY with option 81
- From DHCP network "Enable DDNS update"
- From DHCP network "Enable Option 81 Support" with first option because I want DHCP server always updates DNS
- From configure DDNS (DDNS options) I'll configure the DNS UPDATES TO EXTERNAL ZONES with the forward-zone I want to update.
- SECOND Question: the "Zones to Update for Hosts Using DHCP FQDN Option" is used only for DDNS in Grid?
- I should use the same DNS UPDATES TO EXTERNAL ZONES used for the first case also if I use option 81?
Please, let me know if I'm working properly or if I forgot something.
Thank you,
Fabio Colombo
