IP Netblocks WHOIS Data will tell you

The database contains IP whois data from major Internet Addresses Registries on a daily basis

The resulting database is a joint dataset, post-processed to get unified and consistent format and data. The output format is JSON or CSV where every row is a separate JSON object or CSV row. It allows parallel processing in your systems.

About 20% of records have partly redacted contact information, due to GDPR.

The database comes in two forms

  • Full databases — a full database of all the IP Netblocks for a given date in unified and consistent JSON or CSV format. These files are named in format:
    "ip_netblocks.%DATE%.full.jsonl.gz"
    "ip_netblocks.%DATE%.full.blocks.csv.gz"
    "ip_netblocks.%DATE%.full.contacts.csv.gz", e.g "ip_netblocks.2018-12-19.full.contacts.csv.gz"
  • Daily incremental databases — changes in full IP Netblocks database compared to the previous date. Includes added, dropped and modified IP ranges since yesterday. These files are named in format:
    "ip_netblocks.%DATE%.daily.jsonl.gz"
    "ip_netblocks.%DATE%.daily.blocks.csv.gz"
    "ip_netblocks.%DATE%.daily.contacts.csv.gz", e.g "ip_netblocks.2018-12-19.daily.contacts.csv.gz"

File storage time: every file is available for 3 months since its creation date.
