Practical usage

Useful for Cyber Forensic analysis

Threat investigation and an essential component of any network security solution. Having IPs collected from your or your clients’ firewall logs, you can identify the networks where they have come from as well as their owners.

Trace malicious actors with contact & location details for the IP netblock.

SIEM data enrichment

Provide IP network intelligence (ownership information, ASN, location, etc.) across a variety of SIEM, Orchestration, Automation and Threat Intelligence Platforms.

Threat Defense

Threat analysts can monitor all IP addresses in a netblock containing one or more known malicious IP addresses, and build network behavioral profiles of all these IP addresses over time.
Safeguard an internal network from DOS attacks by blocking IP netblocks that have many known malicious IP addresses.
Block bad actors from misusing your infrastructure.
Block certain netblocks based on location.
Look up the owners of the IP addresses which attack your website.

Threat Hunting

Identify hijacked netblocks more-or-less in real time by getting daily updates for changes in the entire IP Netblocks database.
Enterprises can use IP netblocks database to understand their network attack surfaces.

Enrich your Marketing

By collecting IPs from your web server’s log and supplementing them with IP Netblocks whois data, you obtain a data set from which you can deduce the structure and dynamics of your traffic. Such information can have significant marketing implications, e.g. from which networks you are visited most frequently.

Merger and Acquisitions

Having a network you can possibly be interested in extending, by purchasing neighboring netblocks or find other free blocks for purchase.

Network Filtering and DRM

Provide access to your clients via network filtering (e.g. a software license or a journal subscription), you can identify their networks from netblocks data.
