RFC 1916          Enterprise Renumbering Solicitation      February 1996


3.  Information on Tools

   Information on the tools that were used in renumbering is valuable,
   whether provided as a separate note or as part of an account of a
   renumbering effort. We welcome comments, however detailed or brief,
   on any tools that helped with renumbering, whether or not you intend
   to produce an account of the entire renumbering effort.

   Some areas in which tools may be used in renumbering include:
   -- Identifying what needs to be changed in your network, such as
      configuration files, hosts and servers with embedded or cached IP
      addresses, DNS, access control lists (ACLs), firewalls, routers,
      license servers, and other applications.
   -- Identifying external factors (such as remote servers, routers, and
      Internet registries) that need to be updated to accommodate your
      new numbers.
   -- Identifying dependencies between the different places where the
      numbers must be updated.
   -- Notifying external agents.
   -- Generating the new information (such as routing, configuration,
      and ACLs) required in order to carry out the updates.
   -- Coordinating updates.
   -- Making the updates.
   -- Verifying the updates.
   -- Trouble-shooting and debugging.
   -- Maintaining network functionality.
   -- Informing your users and other affected human beings (such as NOC
      staff) of the changes.

   The most useful tools are those that are, or can be, available to
   other renumbering efforts. For a given tool, it would be helpful to
   describe:
   -- How to obtain it (if not a well-known tool).
   -- What you used it for.
   -- How you used it.
   -- What its strengths and limitations are for these specific uses.

   If a tool was created as part of the renumbering effort, a
   description of exactly what it does should be included. (For example,
   a script to check for IP addresses in configuration files on user
   machines should be described in terms of just what it did to obtain
   the list of machines, what files it looked for, and how it checked
   them.)

   Although the primary goal of this solicitation is to learn what tools
   exist and are useful, we also value specific, experience-based
   descriptions of ways in which tools could have helped even though
   nothing was available during the renumbering to perform these

   functions. Advisories on tools that appear to be useful but in
   practice created further problems may also be considered, as
   appropriate.

4.  Application Information

   Information on applications that require special attention when
   renumbering are of particular interest, since specialized
   applications are among the most difficult aspects of renumbering.  It
   typically requires special intervention with the vendor to provide
   new security keys, new license addresses, new versions of
   applications, or perhaps even new hardware or proms to change the
   hardcoded IP addresses.

   A list of any such applications that required "extra" efforts during
   the renumbering process is valuable. Please include as much specific
   information as possible, including but not limited to: application
   name, version, platform, vendor, operating system, operating system
   version, the steps taken to overcome the problem, and lead times
   needed.

   In particular, any applications that are no longer supported, or
   whose vendor has ceased to do business, are extremely important since
   these applications will likely be some of the more difficult issues a
   renumbering effort will encounter.  Any solutions to these types of
   problems, including replacement applications and proprietary
   solutions, are also sought.

5.  Security Considerations

   This RFC raises no security issues, although accounts of renumbering
   are encouraged to describe any security issues encountered, any tools
   that helped identify or resolve the issues, and the actions taken to
   address them. Submissions should give serious consideration to the
   content and context of issues regarding security.

Appendix  A - Formatting Rules (from RFC 1543)

   Note: there are a set of NROFF formatting macros for the following
   format.  Please contact [e-mail] if you would like
   to get a copy.

3a.  ASCII Format Rules

   The character codes are ASCII.

   Each page must be limited to 58 lines followed by a form feed on a
   line by itself.

   Each line must be limited to 72 characters followed by carriage
   return and line feed.

   No overstriking (or underlining) is allowed.

   These "height" and "width" constraints include any headers, footers,
   page numbers, or left side indenting.

   Do not fill the text with extra spaces to provide a straight right
   margin.

   Do not do hyphenation of words at the right margin.

   Do not use footnotes.  If such notes are necessary, put them at the
   end of a section, or at the end of the document.

   Use single spaced text within a paragraph, and one blank line between
   paragraphs.

   Note that the number of pages in a document and the page numbers on
   which various sections fall will likely change with reformatting.
   Thus cross references in the text by section number usually are
   easier to keep consistent than cross references by page number.
