172.22.1.53 is part of a reserved block. There is no way to do a geoip lookup for it because it may be used in many places by many organizations. It would be like trying to geoip 127.0.0.1

Geoip is working only on public IP's. not working on private ip's like 192.168.x.x , 172.x.x.x, 10.x.x.x etc.

Thanks & Regards,
