Really, really dumb question.....

What would make a DNS server automagically add an entry into its list?

I'm getting ready to generate a couple more Samba servers.  I brought up two of 
them (LINUX60 and LINUX61) for testing.  I brought up both of them, based on my 
static documentation (installing SUSE 10 SP2).  

LINUX60, I bought up last week.  
Last week, I couldn't ping LINUX60, but I could ping its IP address.
This week, I can ping LINUX60.  

This week, I bought up LINUX61 on Monday.
Here it is, Wednesday, and I still can't ping LINUX61.  (The IP address does 
ping)

When I ping some older images (LINUX50-LINUX59), I can't ping the names, but I 
can ping the addresses.  From that, I think that no one else is updating our 
DNS servers, and the automagically something, is looking for something that I, 
perhaps, sometimes is specifying.

Funny, our older SAMBA server, LINUX27 is pingable, but LINUX26 isn't.  (These 
are SLES 8 flavors.)

I think I remember reading that if I bring up the DNS Server code in a linux 
image, that action will cause my machine to automatically, be added to the DNS 
servers list.  I have never, brought up the DNS Server code on any of my 
machines.

I do specify a DNS server address when I create the Linux image, and I think 
I'm pretty good at doing this on all my images.

It has be baffled that some images seem to be dynamically added while other 
images are not.

Any discussion on this?

Thanks
