Roland, At the risk of stating the obvious, ULA does not provide any real-world security... They do not have the E-bit set ;-)
More seriously, ULA can be routed, so, if a ULA route leaks, then your ULA can be reached. Obviously, if your ULA gets a default route, then it can send packets to the Internet (information leak/covert channel). The 'only' advantage of ULA vs. GUA is ease of filtering on a very short and well-known prefix. -éric > -----Original Message----- > From: ipv6-boun...@ietf.org [mailto:ipv6-boun...@ietf.org] On Behalf Of > Roland Bless > Sent: mardi 27 septembre 2011 15:37 > To: 6man > Subject: Centrally assigned "ULAs" for automotives and other environments > > Hi, > > For several reasons (esp. security) those networks > should operate isolated and independent from the Internet.
