* feat(ipconverter): add a tool to convert IPv4 to int and vice-versaFranck Cuny2022-06-184-0/+120
It's sometimes useful to store IPv4 addresses as an integer. This tool helps with the conversion, and also does the reverse conversion. ``` % go run . int2ip 3232235521 3232235521 192.168.0.1 % go run . ip2int 192.168.0.1 192.168.0.1 3232235521 ``` Change-Id: Ic1e44057bca3539b4c183d387c635f69f5bf3f36 Reviewed-on: https://cl.fcuny.net/c/world/+/441 Tested-by: CI Reviewed-by: Franck Cuny <franck@fcuny.net>
