Best way to get location for an anonymized ip address

General

1

I have a WordPress plugin that stores information about failed login attempts. This information includes the IP address of the user. For GDPR Compliance the address is anonymized, so for example 142.250.74.142 becomes 142.250.74.0, 31.13.72.36 becomes 31.13.72.36 and so on.

An admin can later get geolocation information for a failed login attempt using IPinfo. Currently the lookup is made using the anonymized address, i.e. 142.250.74.0, but I’m unsure if that the best way and if the results are reliable?

Can the IP addresses in the range 142.250.74.0-142.250.74.255 have different geolocation results, and if, is there a way to query the results for a range of ip-addresses and get multiple geolocation results?

First of all, thank you for posting on the community. Really appreciate that :slight_smile:

Can the IP addresses in the range 142.250.74.0-142.250.74.255 have different geolocation results

Yes, IP address ranges can cover multiple geolocations.

In this case, definitely use the IPinfo CLI, particularly the summarize command. Here is a blog on this. The IPinfo CLI’s summarize command accepts IP address range inputs.

IPinfo Summarize

First, let’s look into summary level information of the range: 142.250.74.0-142.250.74.255.

Code

ipinfo ► ipinfo summarize 142.250.74.0-142.250.74.255

Output

Summary
- Total   256
- Unique  256
- Anycast 0
- Bogon   0
- Mobile  0
- VPN     0
- Proxy   0
- Hosting 256
- Tor     0
- Relay   0

Top Domains
- 1e100.net 256 (100.0%)

From the input IP range, we can see 3 different cities and 3 different countries.

IPinfo Bulk/Batch lookup

Now, let’s say the IP address range is too big, and you need more granular information for each individual IP address. In that case, use CLI’s bulk command, which supports IP ranges as well.

Code

ipinfo bulk -c 142.250.74.0-142.250.74.255 > ip_result.csv

Output: ip_result.csv

This command will generate a CSV file containing information for each individual IP addressses.

Please let me know if you have any further queries. Happy to help!
