[NCSA-discuss] DNS Questions

[Leo Guzynski]

On the topic of DNS registration:

I have been changing the IP addresses of our servers.  There once was a 
form for changing the IP address of a registered DNS server.  The last 
time I had to do such a thing, there was only one registrar. :)    Now I 
cannot find that form or even the handle for the DNS server. 

There are too many domains to just modify each one individually.  Not to 
mention that I do not even control all of the domains.  Any help 
suggestions?


And on to the topic of changing DNS servers and addresses:

Why do I constantly hear that it takes up to 3 days to make a change?  
Yes many years ago we have all experienced problems but today?  I am not 
giving anyone a hard time, but I am curious what people are REALLY 
seeing.  Recently (as noted) have have changed both DNS servers and IP 
addresses.  For the most part everything was as instantaneous as 
specified in the SOA record or the TTL. 

When planning a change, I bump those numbers down to something like 15 
or 30 min.  I do that about a week prior. 

*I* have found that old hosts are not hit after more than a couple of 
hours.
