guys.. I have a thought...
I am a charter fiber customer..
AND they use lots of 1918 address for management even some customer links.
I have seen this on all the cable providers..
unlike Sprint/MCI/ATT they don't use 100% RW on all their equipment..
then they leak because the BGP is not filtering properly..
A DNS lookup for a RFC1918 in-addr.arpa record is unrelated to BGP or
If you want to generate an RFC1918 in-addr.arpa query to the AS112
servers do the following
Default Server: localhost
origin = prisoner.iana.org
mail addr = hostmaster.root-servers.org
serial = 2002040800
refresh = 1800 (30M)
retry = 900 (15M)
expire = 604800 (1W)
minimum ttl = 604800 (1W)
Authoritative answers can be found from:
10.in-addr.arpa nameserver = BLACKHOLE-1.iana.org
10.in-addr.arpa nameserver = BLACKHOLE-2.iana.org
BLACKHOLE-1.iana.org internet address = 220.127.116.11
BLACKHOLE-2.iana.org internet address = 18.104.22.168
Your query will then be included in John's statistics. You BGP filters
will not stop it.
