Hi Alexander,

Well, so far you have me stumped. But that's why I like being here - it's a
learning experience. So I'll work with you, and maybe we both learn something.

Does this happen when something (even your servers no less??) is booted up, and
requesting an address, or does it happen, randomly, during the day? Either way
pretty scary, no? If it happened with the servers, using static IP addresses,
it's not a DHCP issue. You're just using DHCP exclusions as a workaround.

So it really is an IP address issue? I was thinking maybe a nic hibernation.
How did you know to try using another IP address?

Does this just affect Internet access? Any internal symptoms? Right now, I'm
thinking router problem. Any relevant router logs?

Why do you have servers accessing the Internet, if I may ask?

Let's start from the beginning. When did this first happen? Had you made any
network changes previous to it happening? Maybe a new firmware on the routers?
