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. &nbsp;Also the networking config for production servers should not be changing often, so there is very little gain in using DHCP for that. &nbsp;Same thing goes for workstations that are stationary (as in they never leave the office). &nbsp;You could use DHCP for those workstations, but personally I would just configure them manually.<br />
<br />
Summary:<br />
Servers -- configure manually.<br />
<br />
Workstations -- I prefer configure manually, but reserving IP's through DHCP should be fine as well -- up to you. &nbsp;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.<br />
<br />
Laptops / mobile devices / etc -- use DHCP with Dynamic DNS normally and without reservations.<br />

Thanks for the reply.<br />
<br />
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.<br />
<br />
2, for laptops point to the dhcp server <br />
<br />
3, also i can find the file db.dyn.example.org.jnl under the db.dyn.example.org.jnl.<br />
Please help with the above doubts. Thanks in advance.<br />

Correct.<br />

Is that a question? :p &nbsp;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.<br />
<br />
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<br />
<br />
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.<br />
<br />
Sir, iam sorry for these doubts please help iam eager to understand. Thanks in adavance

<div>
Sir, Thank you very much , great support. you have lastly stated converting all of the static zones to dynamic , may i know the reason and advantages please
</div>


<div>
If you want to know all about static vs dynamic zones, start a new question ;)

<div>
very much proud to get this support

Dear Experts:<br />
Configured ddns on ubuntu server 10.4 the same is working fine, To install and configure i followed the <a href="http://www.debianadmin.com/howto-setup-dhcp-server-and-dynamic-dns-with-bind-in-debian.html" rel="ugc">http://www.debianadmin.com/howto-setup-dhcp-server-and-dynamic-dns-with-bind-in-debian.html</a>, this configuraton created two sets of zone files one for static zones (forward and reverse)and other set for dyanamic (forward and reverse).<br />
Have the below doubt please help<br />
&nbsp;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 , &nbsp;iam confused please help me how to handle this, request help on how to handle this.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).
