[comp.protocols.tcp-ip] What does host != addr mean?

peiffer@umn-cs.cs.umn.edu (Tim Peiffer "The Net Guy") (12/19/90)

One of the departments around here has a machine that consistently
gives error messages nres_gethostbyaddr: host != addr.  I can usually
track problems like this down to misconfiguration in the zone tables
for the nameserver.  This problem is not as simple.  The machine that 
gives this error messageis a Sun 4/60 running SunOS 4.1 using the
Sun libc.so hack recently released.   What does this error message mean??
