-.96.15.253 (**useable** - reserved for future use(?))\\
-**208.96.15.254** for **BALUG** use\\
-.96.15.255 broadcast
-Note that **208.96.15.254** is principally **reserved for BALUG** use.  Services that aren't BALUG's
+linuxmafia.com - see linuxmafia.com (& %%w%%ww.linuxmafia.com) DNS data (e.g. for SF-LUG list)
-or conflict or potentially conflict with what BALUG wishes to use on port(s) on that IP may
-get "bumped" from that IP address (e.g. the non-BALUG service reconfigured so it doesn't
-run or also run on that IP).  Note also that in some/many cases BALUG may have no objection
-or conflict with some common services not specific to BALUG also running on 208.96.15.254
-(so those may simply peaceably coexist and not or not likely be "bumped" off of that IP).
-Some background/references/excerpts on the IPv4 addresses follows:\\
+IPs not used for BALUG/%%[%%L]UG(s) may not be particularly detailed here\\
