I need have some windows logs that come in via forwarders that contain an IP address that I need to do a reverse lookup on. You can easily do this at search time, however the the IP addresses in the log are DHCP and frequently change. So i need to insert a field for the name at index time. Is this possible? I have read a previous post that said there was not a way but it was an older post so I was wondering if it may be possible now?
