If I had to guess, I would guess that renumbering is likely required to get=
it into a more portable address assignment from a multi-homing perspective=
. Look at the whois information below
If I were hosting a root server or something similar, I would certainly wan=
t it segregated enough that I could manage multi-homing for that address pr=
efix outside of my other networks. =20
In this case, I'd assume UMDNET-1 may have monetary or administrative polic=
ies regarding the ability to be multi-homed and the degree to which it can =
be, however providing multiple links to UMD-ROOTD-NET is likely much easier=
because those decisions (or cost of connections) don't necessarily need to=
affect UMDNET-1

So really stupid question, and hopefully it's just me, do I need to do some=
thing=20
on my servers?=20
Second question: I know that renumbering is important in the abstract, but =
is there=20
really an overwhelming reason why renumbering the root servers is critical?=
Shouldn't=20
they all be in PI space for starters?=20
