IP netblocks refer to series or ranges of successive IP addresses that are part of the same block, such as 8.8.8.0–8.8.8.255. RIRs assign IP netblocks to netblock owners, typically ISPs and large enterprises that require a sizable number of IP addresses.
IP Netblocks Owner Lookup retrieves data from one of today’s most comprehensive IP Netblocks WHOIS Database that contains information on more than 10.4 million netblocks and tens of thousands of unique ASNs and ranges refreshed daily.
Outputs from our IP netblocks lookup tool are formatted for intuitive data reporting with the most relevant ownership details readily available. The lookup reports can be easily shared with colleagues and relevant stakeholders via permanent URLs.
All of our IP netblocks data is also accessible in our extensive database, available in JSON or CSV with consistent and unified ranges.
