I was concerned about this too after noticing 1.x.x.x connections to our 
streamserver, knowing the ancient Linux firewall/router forces 1.1.1.1 
as the address of the interface used for PPPoE - I guess that was common 
usage back when? - but see the APNIC bods are onto it, also noting that 
1.0/16 and many/most 1.1 (other than 1.1.1/24) are already allocated:

Just as well, as I had to address the ADSL bridge within 1.1.1/24 ..
