Hello,

I found out that if I deny users going to 255.255.255.255, it is the same as
if I denied going to unknown hostnames:

acl bogus dst 255.255.255.255
http_access deny bogus

I can confirm this from the sources. Why it is done like this I don't know.

Is this wanted behaviour, a side effect of something (probably when
getnostname() returns -1) or a bug? Should I fill a bugreport?

It is explicitly done in the source so I can only assume there is some intention behind it, but the source history gives no clues (added in acl.c revision 1.25 1996/07/23).

But at least it is somewhat consistent:

IP matches uses 255.255.255.255 if no address could be found (dst,dstasn acl)

host/domain matches uses "none" if no host name could be found (dstdomain/srcdomain acls).

Henrik
