Added a section for attempting to bind to an IP not present on the host

  }}}
  will incur the same error message. Apache binds to *:80, and then tries t=
o also bind on 1.2.3.4:80, which fails because it is already bound by the f=
irst line. If you're binding on *:PORT, you do not need to also bind on a s=
pecific IP. =

+ When trying to bind to an IP and port not present on the host system, apa=
che httpd will fail to start. For example, if the network interface has the=
 IP 1.1.1.1 assigned, and Listen 2.2.2.2:PORT is used, this error will be t=
riggered. In the event that the IP will change on a regular basis, it is re=
commended to use Listen PORT or Listen *:PORT instead.

  Unix based systems disallow non-root users to bind processes to port numb=
ers below 1024. Get root!
