The home page gets cards for the newest and oldest kept route, the newest and oldest updated AS, the AS with the most prefixes, the ASes with a single prefix and fifteen well-known networks. Two more cards count the bogon announcements and the prefixes with several origin ASes. They link to the new pages /bogons and /multiple-origins, which list up to 1,000 entries each. The new package internal/bogon tells reserved prefixes and AS numbers, from the IANA special-purpose and address space registries. Table.Overview walks the table and lets the read lock go every 10,000 prefixes. The server works the cards out once a minute and serves that copy. A new index on asns(last_seen) finds the newest and oldest updated AS. Model: opus-5-5
