I work for MaxMind and it was pointed out to me that a popular blog post of ours around here was this post from 2015 showing how to build an MMDB using Perl.
Well, it's 2020 now and we've got a post showing how to enrich your MMDB files using Go now.
Just wanted to let you all know. If you have any questions feel free to reply here or create an issue in the github repo.
