    Hi,
    
    I am afraid it does affect RFC 1918 addresses, at least did it on my 
    network.
    I have a WLAN (11 Mbps) at the first time i could not realise 
    what the .... was going on. Public ip addresses randomly changing
    by 20 i.e:
    99.66.18.125 - 99.66.18.144 etc
    But 2 days ago i saw an RFC 1918 address 10/8 prefix.
    I have a router with network 10.0.0.0
    I only saw it once and then nothing again.
    
    
    
    Regards
    
    Kostas
