Navigating Post-Transfer Geolocation Hurdles: A Practical Guide for IP Buyers

Acquiring new IPv4 blocks is a critical milestone for scaling your network operations. However, buyers occasionally encounter an unexpected post-sale hurdle: geolocation mismatches.

Geolocation is the process of identifying the real-world physical location from which an IPv4 block is being announced.

Because IP geolocation is largely automated and handled entirely by independent third-party vendors rather than registry databases or brokers, transferring a block to a new organization or region doesn’t instantly flip a switch across the global internet. Automated mapping engines rely on continuous inputs like BGP routing updates, traceroutes, and historical records, which means legacy associations can linger for weeks.

When a freshly acquired block still points to its previous region or owner, it can trigger geo-blocking, localized service errors, or friction with automated security filters. Because this mapping process is completely external to the transfer ecosystem and governed by third-party algorithms, it is impossible for brokers to predict, control, or adjust ahead of time.

Fortunately, navigating this interim period is straightforward if you take a proactive approach.

Directly Submit Updates to Major Geolocation Vendors

The fastest way to correct misattributed routing data is to bypass waiting for automated systems and submit update requests directly to the primary database providers. Prior to making these update requests, make sure that you are actively broadcasting the IPv4 block in question from the location you wish. Each major vendor maintains dedicated submission channels for network operators:

• MaxMind: Use the MaxMind GeoIP Location Correction form to submit your newly acquired IP blocks, target country, region, city, and postal code. Make sure to use a corporate email address tied to your organization’s official domain or ARIN POC records.
• IPinfo: Submit corrections through the IPinfo Corrections Portal, which accommodates both individual IP ranges and bulk corrections via geofeeds.
• Other Key Providers: Reach out similarly to other mapping entities like IP2Location, DBIP, Digital Element and Neustar to ensure broad propagation. Some of these geo-providers accept emailed update tickets. The email should come from one of the ARIN POC email accounts or at least an email from the same domain name.

Ensure Your Core Routing and WHOIS Data Match

While waiting for vendors to process updates, verify that your fundamental administrative records are clean:

• WHOIS Registries: Ensure that the registrant, administrative, and technical contact details correctly point to your corporate entity and operational country.
• BGP Routing: Make sure your Autonomous System Number (ASN) properly announces the block so that automated network mappers see the new traffic origin path.

Setup a Geofeed File

A geofeed file is a simple text file in CSV format which contains a line for every IPv4 block you wish to geolocate along with its location data. The file is normally hosted under the operator’s domain name.

Some RIRs, including APNIC and RIPE, have a geofeed attribute right within their database where registrants can point to their publicly accessible geofeed file. ARIN does not have such an attribute, but many registrants will add the location of their geofeed file in the Whois Comments section.

Use a VPN as an Interim Bridge

While you wait for global geolocation databases to process your update requests, which is a process that can take anywhere from a few days to a few weeks, your internal applications, testing environments, or remote teams might experience access friction. Many travelers are familiar with VPNs that both encrypt and relocate IP address location.

Deploying a reliable Virtual Private Network (VPN) or enterprise proxy solution during this transition window allows your team to route traffic through the expected geographic region, bypassing localized security trips or regional blocks until the global IP databases fully ingest your new routing configuration. This is an option if you aren’t ready to broadcast the IP addresses in your desired location but wish them to appear that they are so you can make headway on the geo-updates.

Final Thoughts

A successful IPv4 acquisition involves planning beyond the transfer itself. Keeping registration and routing information current, submitting corrections to geolocation providers, and publishing a geofeed can help buyers address outdated location data and prepare their new addresses for use.

While third-party providers determine when their databases update, a proactive approach can help your team manage the transition with clearer expectations.
