I am collecting BIND logs and being parsed properly. However wanted to seek your ideas if below can be achieved using graylog pipelines?
among the bind logs one of the field I am collecting is client who is querying which is coming as IP addresses. If I can do a PTR or ping -a to that host I get the hostname that way it is pretty easy to identify hence wondering if function or pipeline can be written to achieve the same?

I wrote a simple www server with perl. The server receives http queries (that graylog HTTP data adapter can send), makes a reverse dns query with the IP address found in the query and replies with a json reply. Works nicely, but of course it is a hack.
If I understand correctly, version 2.5.0 will support DNS queries natively (https://github.com/Graylog2/graylog2-server/pull/5274).
@blason the upcoming 2.5 will have DNS Lookup Table as @jtkarvo already pointed out.
