Description

Pri testovaní TS2.5 pre PostgreSQL som našiel zvláštne popísané správy v prípade reportu pre rozsah IP adries, ako vidno z ukážky nižšie, konkrétne Target.IP4.{ip,max,min}

{  
  "ID":"0a7063ac-8f20-468f-ba7a-afcef12deeeb",

Minimum a maximum špecifikujú /24 rozsah, v tomto prípade 147.229.104.0 - 147.229.104.255, je ale nastavená aj položka ip, na hodnotu minima. Normálne by som to akceptoval, že sa jedná o z pohľadu udalosti nejako významnú adresu z daného rozsahu, ale podľa whois databázy je to adresa siete.

Celkovo sa jedná o niekoľko rozsahov (vždy /24) ale tiež niekoľko detektorov:

                    node_name                    | count
-------------------------------------------------+-------
 {cz.cesnet.mentat.warden_filer,cz.vutbr.hpscan} | 32007
 {cz.cesnet.mentat.warden_filer,cz.nic.dionaea2} |  5631
 {cz.cesnet.mentat.warden_filer,cz.nic.dionaea1} |  4932
 {cz.cesnet.mentat.warden_filer,cz.nic.kippo}    |   893

Moja otázka: Je IP = IP_min if IP_min != IP_max; očakávané chovanie?
