Hello guys, i am trying to map my ips with the office name that it belongs. My idea is to have a json or something that i can access with logstash in order to do the mapping to get the data. Is that possible or is any way to do that? Regards ---

If you have a very small number of offices, a cidr filter per office might work. Or you might try a [translate](https://discuss.elastic.co/t/create-custom-geoip-database-for-logstash-5-2/79473/13) filter. Or, I think, you could [build](https://blog.maxmind.com/2015/09/29/building-your-own-mmdb-database-for-fun-and-profit/) a custom geoip database and use a geoip filter. ---
