I have swapped IP addresses between hosts space-s and apollo7-s on DNS servers. Only 3750 insist on old values in its hosts table. There is not possible to ping apollo7-s from 3750 by name. It is possible by number only.
ss-s01-1#sh hosts
Default domain is fzu.cz
Name/address lookup uses domain service
Name servers are 147.231.26.154, 147.231.126.127

apollo7-s.fzu.cz None (temp, OK) 0 IP 10.26.202.30
