Bot prevention : Known bots IP service

[GoulvenF]

Version française (google translate)

Problem

• The IpFilterService (Bot prevention : IP limit filter #316) will need blacklist and whitelist ips

Solution

• We need to develop a service which :
  • grabs search engine IPS and badbots ips
  • provides methods that allow to check a given IP

Requisites

• must be fast
• should be a spring approach, or something that can easily be applied in spring context

Tips / work tracks

• First approach is to grab from online dictionaries, such as badbots.com
• Another approach could be reverse dns the first connection and check its in a known bot list, but not so great i thing
