ddns on ubuntu server

Dear Experts:
Configured ddns on ubuntu server 10.4 the same is working fine, To install and configure i followed the http://www.debianadmin.com/howto-setup-dhcp-server-and-dynamic-dns-with-bind-in-debian.html, this configuraton created two sets of zone files one for static zones (forward and reverse)and other set for dyanamic (forward and reverse).
Have the below doubt please help
 few systems and servers requires static ip and the same to be always reserved or assigned to these systems and servers please note including gateway and name servers. Should i manually assign the ipaddress , gateway and dns entries for these systems and servers or will get the details from the dhcp when configured for dhcp ,  iam confused please help me how to handle this, request help on how to handle this.

For servers I would definitely manually configure all of that -- you don't want your production servers relying on a DHCP server to be available and functioning in order to get their network config info.  Also the networking config for production servers should not be changing often, so there is very little gain in using DHCP for that.  Same thing goes for workstations that are stationary (as in they never leave the office).  You could use DHCP for those workstations, but personally I would just configure them manually.

Summary:
Servers -- configure manually.

Workstations -- I prefer configure manually, but reserving IP's through DHCP should be fine as well -- up to you.  Just remember that if the DHCP server goes down, and the workstation's lease expires during that downtime, that you will have to configure it manually anyways.

Laptops / mobile devices / etc -- use DHCP with Dynamic DNS normally and without reservations.

Thanks for the reply.

1. Sir, I will configure all the servers and work stations with manual ip address i think i shoud add the hostnames and ip address in the forward and reverse zones of the static zones, please suggest me is this correct.

2, for laptops point to the dhcp server

3, also i can find the file db.dyn.example.org.jnl under the db.dyn.example.org.jnl.
Please help with the above doubts. Thanks in advance.

Correct.

Correct.
3, also i can find the file db.dyn.example.org.jnl under the db.dyn.example.org.jnl.
Is that a question? :p  FYI .jnl files are journal files, which are used when a DNS zone is dynamic.

Thank you very much , very much sorry for one final doubt.

1. I was thinking if the hostnames mapping to the ip address and reverse dns details are present in the static zones then if we name the work station or desktops by pointing to the dhcp server, the exact ip address which is presnt in the static zones will be appiled to the newly named host(work station or desktop), please tell me should the ddns behave something like this or for this to happen should reserve the ip address for the particular mac in the dhcpd.conf

2. as per the document created the dynamic zones(forward and reverse zones unde /var/cache/bind) i was thinking the these dynamic zones will be written by the bind but instead new file got created , db.dyn.example.org.jnl (journal files) is it based on these dynamic zones this new journal got created.

Sir, iam sorry for these doubts please help iam eager to understand. Thanks in adavance

For the servers and workstations that you will be adding into the static zones, you should remove dhcp from the flow entirely.  You should be configuring each host individually, in DNS and on the machine, and not using dhcp or ddns at all for them.
2. as per the document created the dynamic zones(forward and reverse zones unde /var/cache/bind) i was thinking the these dynamic zones will be written by the bind but instead new file got created , db.dyn.example.org.jnl (journal files) is it based on these dynamic zones this new journal got created.
http://www.bind9.net/manual/bind/9.3.1/Bv9ARM.ch04.html#dynamic_update

You can use 'named-journalprint db.dyn.example.org.jnl' to see the contents of the journal.

In BIND 9.9, which is still in alpha, there is a new command 'rndc sync' which will commit the journal to the zone file on disk.  The proper way to do that now is to rndc freeze / rndc thaw.

On a related note, I recommend converting all of your static zones to dynamic.
