How does dhcplb handle ip conflicts and concurrent DHCP servers?

In the README diagram, there's a cloud of DHCP servers, are they working concurrently? If so, is that support by dhcplb or is facebook doing custom code internally?

yes, they are all working concurrently, and independently. The server is just dhcplb in server-mode, as discussed at https://engineering.fb.com/2019/05/28/data-infrastructure/dhcplb-server/

I tried running dhcplb in server mode with the code on this repo and it crashes with a segfault. I'd have to go dig in my logs to share them. The code works fine in relay mode though.

thanks - let us know once you have the logs!
