BGP Table Watch is a recurring IPexpToBe / Network freak series tracking how the global Internet routing table changes over time.
The weekly report focuses on IPv4 prefixes, IPv6 prefixes, visible ASNs, new ASNs, large route additions, withdrawals and routing-table growth trends. Daily X updates provide a short snapshot, while Monday posts provide a deeper weekly summary.

Methodology note
The first version of this series uses public Potaroo/CIDR Report time-series and weekly per-origin-AS delta tables. A later version will add full MRT/RIB snapshot comparison so the report can list exact prefixes added and removed during the week.
