Hello, @subgero hope you are doing well.

172.67.68.102 doesn’t belong to a private range of ipv4 addresses.

172.16/12 range of private addresses goes from 172.16 to 172.31, where as you can probably see 172.67 falls outside of that range.

If something in your internal infrastructure overlaps with this range, you are using a public range internally, which you shouldn’t.

Hope it helps :wink:
