It might be useful to have an option to print the original name that was given in addition to the numerical name. For example like this: foobar.weebly.com (199.34.228.54) is alive foobar.weebly.com (199.34.228.53) is alive There is an option '-n' that you can combine with '-A', but it does a reverse-DNS lookup, so you might not get the same name, and later you don't know what address was for what host. > If you need exact compatibility with old versions, you can: > > - compile fping with --disable-ipv6 (or use a wrapper, and call > 'fping -4') > > - compile fping with --enable-ipv6 and rename it to fping6 (same as > 'fping -6') > > 2) So "--enable-ipv6" implies "--disable-ipv4"?

When you call the fping binary 'fping6' (with a sym-link, for example), it is going to implicitely set the '-6' option at runtime. Bad idea?
