Hi All,

I'm looking for a DDNS package that I can setup on a CentOS 5 server for potentially thousands of devices deployed at thousands of sites world wide.

Normally dynamic DNS works something like this:

curl http://dyndns.org/update.cgi -F domain=foo.example.net -F password=UNPRINTABLE -F >address=1.2.3.4

Since you're talking about bind as a solution, I guess you're basically talking about implementing an alternative to dyndns.org (i.e. the hub) rather than a dyndns client (i.e. the spokes) ?

In that case, why are you talking about bind? You're not thinking of clients pushing updates to the hub via NOTIFY + IXFR, are you? Because I don't see how that could possibly work.

This is exactly what I'm trying to do and why I asked the question here. If Bind is not the right tool, what then is? TIA, again Chris -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
