My config file says

One is the University of Potsdam, which seems a likely pool member. The other
is the National Information Infrastucture Development Office in Budapest -
again, I would not think that too unlikely.

The zones are listed at http://www.pool.ntp.org/zone/europe but I have no idea
how to find out which servers are in each pool.
In fact it is not the same addresses each day. The day before I mentioned it,
the report gave the IP of Research Machines, in Oxfordshire. Again, a likely
member of a pool.
