145.Pp
146In
147.Fx 5.2 ,
148the default behaviour of
149.Nm
150was changed to treat local-to-local talk requests as originating
151and terminating at
152.Em localhost .
153Before this change, it was required that the hostname (as per
154.Xr gethostname 3 )
155resolved to a valid IPv4 address (via
156.Xr gethostbyname 3 ) ,
157making
158.Nm
159unsuitable for use in configurations where
160.Xr talkd 8
161was bound to the loopback interface (normally for security reasons).
