I can see the logic of having an internal DNS entry 'seednodes.internaldomain.com',
this might only have 3 defined seed nodes out of 100, but the benefit is single point configuration, no need to edit configs across 100 machines, easily redefinable on the fly as needed...

Seems like a lot of complexity for a very small win (how often do you
bootstrap new nodes?  if you only need a handful of seeds, what's all
that hard about listing them all on all nodes?).  I prefer simple and
predictable, and trying to do this with round robin DNS seems to be
neither, to me.
