I'll be honest, I didn't deep dive into too many options. So I didn't know
about avro-mocker, for instance. Might be worth checking out.
I did check out JFairy and Faker (Java version), and neither of them have
particularly good performance. I am kinda thinking about working on that
library from Confluent to let it integrate with them optionally.
FWIW, you can use the regexes to generate ip strings, etc. AFAIK, this
would do IPv4 IPs:
`[\d]{,3}\.[\d]{,3}\.[\d]{,3}\.[\d]{,3}`
