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..
lol either they deliberately announce rfc1918 via network 10.0.0.0 or redisting igp into bgp...
priceless.

Uhm, incorrect.
A DNS lookup for a RFC1918 in-addr.arpa record is unrelated to BGP or
BGP filters.
If you want to generate an RFC1918 in-addr.arpa query to the AS112
servers do the following
nslookup
Default Server: localhost
Address: 127.0.0.1
set querytype=any
10.in-addr.arpa
Server: localhost
Address: 127.0.0.1
Non-authoritative answer:
10.in-addr.arpa
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 = 192.175.48.6
BLACKHOLE-2.iana.org internet address = 192.175.48.42
Your query will then be included in John's statistics. You BGP filters
will not stop it.
