The global BGP table keeps moving every day. This weekly BGP Table Watch snapshot tracks IPv4 prefixes, IPv6 prefixes, visible ASNs and the largest routing-table changes reported during the last week.
The goal is not to alarm on every change. BGP is noisy by design. The goal is to build a simple operational habit: watch the size of the routing table, notice large origin-AS changes, and keep an eye on where new ASNs and route withdrawals appear.
Weekly snapshot
| Metric | Current value | 7-day change |
|---|
| IPv4 active BGP entries | 1,085,085 | +3,809 over 7 days |
| IPv6 active BGP entries | 257,555 | +596 over 7 days |
| Visible ASNs in BGP | 79,571 | +14 over 7 days |

Important methodology note
This report uses public Potaroo/CIDR Report time-series and weekly per-origin-AS delta tables for the broad daily/weekly view. When a RIPE RIS prefix-diff file is available, the article also includes exact added/removed prefix samples from full MRT/RIB snapshot comparison.
The exact prefix-diff section is collector-scoped: it reflects RIPE RIS rrc00 visibility, not every possible global vantage point. That is still useful for a repeatable weekly BGP-change digest, but large operational conclusions should be checked against multiple collectors.
Why this matters
- Capacity planning: routers, route reflectors and firewalls must handle the continuing growth of IPv4 and IPv6 tables.
- Troubleshooting: sudden per-AS growth or withdrawal can point to deaggregation, leaks, migrations or visibility changes.
- Internet operations: new ASNs and large route deltas show how the public Internet keeps changing every week.
