FYI, some name server still returns the old address:
--------------------------------------------------------------------------------
$ host 132.195.125.5
5.125.195.132.in-addr.arpa domain name pointer grid-ce.physik.uni-wuppertal.de.
--------------------------------------------------------------------------------
$ host 132.195.104.99
99.104.195.132.in-addr.arpa domain name pointer grid-ce.physik.uni-wuppertal.de.
--------------------------------------------------------------------------------
$ host grid-ce.physik.uni-wuppertal.de.
grid-ce.physik.uni-wuppertal.de has address 132.195.104.99
