URL Option

The URL DHCP Option Number species a URL which may be displayed by a DHCP
client after boot and launching a web browser.  URLs are specified in RFC
1738.

This option can / should be used in place of option 72 which only specifies
an IP address for a web server.  Providing a full text URL supercedes the
information in option 72 and provides greater flexibility to system
administrators.

The code for this option is 112.   Its minimum length is 1.

  Code   Len     URL
 +-----+-----+----+----+----+----+----+--------
 | 112 |  n  | h1 | h2 | h3 | h4 | h5 | ...
 +-----+-----+----+----+----+----+----+--------

----------------------------------------------------------------------------
------

If option number 112 has already been assigned (it was lsted as unassigned
on ftp://ftp.isi.edu/in-notes/iana/assignments/bootp-dhcp-parameters as of
1/12), then I will gladly accept whatever option number available.
