224.21.169.151 : is a bogon IP which means that it should not appear on the Internet.

Description:

Some IP addresses like 224.21.169.151 and IP ranges are reserved for special use, such as for local or private networks, and should not appear on the public internet. These reserved ranges, along with other IP ranges that haven't yet been allocated and therefore also shouldn't appear on the public internet are sometimes known as bogons.

Because bogon IP addresses don't belong to a specific user or server on the internet, so there's no way to geolocate them. Therefore our IP geolocation API won't return location information for IP addresses within bogon ranges, but it will return a bogon field to indicate that the IP address is a bogon.
