Interesting.  Is there a Debian specification that explains the 
127.0.1.1 entry?

Gene -- by "it", do you mean the 127.0.1.1 entries?


> I'm not sure what you mean by scope. 127.0.0.0 is /8 isn't it?


That is my understanding, and what Wikipedia says:

https://en.wikipedia.org/wiki/Reserved_IP_addresses says:

127.0.0.0/8 	127.0.0.0–127.255.255.255 	16777216 	Host 	Used for 
loopback addresses to the local host.[1]


So, both 127.0.0.1 and 127.0.1.1 are in the IPv4 special use address 
block 127.0.0.0/8.
