 %description
-ipv6calc is a small utility written in programming languate C to manipulate
-(not only) IPv6 addresses. Intentions were convering a given IPv6 address into
-compressed format, convering a given IPv6 address into the same format like
-shown in /proc/net/if_inet6 and (because it was not difficulty) migrating the
-Perl program ip6_int into. Now only one utility is needed to do a lot.
-
-This utility is also used to extend features on network-functions-ipv6 library,
-used by initscripts-ipv6.
-
-Note: this tool got also its freshmeat / ipv6calc page (not maintained by the
-author)
-
-Hint: take also a look at the Advanced Network Management Laboratory / IPv6
-Address Oracle if you want to learn more about IPv6 addresses.
-
+ipv6calc will do some format changes and calculations for you
+beside this it is able to display information and filter
