Handle and log invalid IP address errors #25
Description
Would you mind including logstash-plugins/logstash-filter-anonymize#8 from the now obsolete anonymize plugin?
For us this is still an issue and we need to patch our Logstash instances with this patch.
I didn't try yet but I guess the changes will apply to the fingerprint plugin as well. If you agree, I could open a new clean PR for this plugin with the changes.
