il piccolo problema è che se si prova ad interrogare senderbase su
qualche indirizzo IP in quel range, salta fuori qualcosa di diverso
 
dig +short 
16.2.0.192.query.senderbase.org
 TXT
 
"0-0=1|1=SU-NET-AS|2=0.0|3=0.0|4=3233910|7=0|20=|40=0.0|41=1.5|43=0.6|44=37.2|45=N|46=24|48=24"
 
e sin qui, ci sta tutto, ma se proviamo con l'IP successivo...
 
dig +short 
17.2.0.192.query.senderbase.org
 TXT
 
"0-0=1|1=CHINA EDUCATION AND RESEARCH NETWORK CENTER|2=6.1|3=6.2|4=202460|6=0|7=54|8=15700480|9=12589|20=|40=0.0|41=1.0|43=0.0|44=100.0|45=N|46=24|48=24"
 
ecco, ora... mi spiegate l'arcano ? Mica per altro, ma qualquaglia non
mi cosa

a me, in questo momento:
