Question DNS


Hi,

I'm using centos 6,
Linux 2.6.32-71.el6.i686 i686 i686 i386 GNU/Linux


I need to configure a DNS server at my home,but my ISP provider is running a DHCP server it seems,(i.e.),I'm not getting a standard IP,it keeps on changing.

I goggled and came to knew that i can configure DDNS,but I've few others dough too.I can use free domain names searching the web.But the problem is that,what server should i configure,(i.e.)cachingnamed server or DNS or DDNS...:-?

Please suggests.

Thanks in advance...

You have not said what you want it to do, so it is very difficult to say what exactly will do it. If you just want to improve look up of external web site addresses from apps on your network, then it is probably just caching. If you want something else, then its something else.

Incidentally, DHCP is one of the ways that your ISP can assign an IP to your interface to the 'net. And, the ISP probably is running DHCP internally for other reasons, so whether or not the ISP is running DHCP, the issue is that you do not have a static IP address facing the internet.

In that context, something like ddns can be useful, but essentially it solves the problem of 'I am outside my home network, and I want to access my network, but the IP may have changed, and I want to access it by IP'. If you have a different problem that you want to solve, then it may not be the solution.
