What is New prefix (first announcement)?

A first-seen prefix is an IP block we observe in BGP for the first time within our recent observation window. Because our dataset is young, this currently means new-to-us — not necessarily new to the global Internet. New prefixes are normal during network growth, leasing, or de-aggregation, but a sudden burst can signal address-space deployment or the hijack of previously-unrouted space.

Frequently Asked Questions

What is a BGP New prefix (first announcement)?

A first-seen prefix is an IP block we observe in BGP for the first time within our recent observation window. Because our dataset is young, this currently means new-to-us — not necessarily new to the global Internet. New prefixes are normal during network growth, leasing, or de-aggregation, but a sudden burst can signal address-space deployment or the hijack of previously-unrouted space.

Where does this data come from?

Every event is detected from live BGP updates collected across 23 RIPE RIS route collectors worldwide, ingested into a ClickHouse time-series store and re-evaluated every few minutes. No third-party feed is resold; the analysis is original to WorldIP.io.
