AS16731 announces 3 IPv4 prefixes covering 1,024 addresses and 0 IPv6 prefixes.

About this network

Three blocks, two netname counters, and the number between them is missing.

What it's used for

• A bank's network. Three IPv4 prefixes announced from Canada, no sixth-version space, one thousand and twenty-four addresses, through four observed BGP neighbours.

Notable

• The AS handle is the two letters for an autonomous system, the number, a dash, and the holder's full four-word name.
• All three blocks are registered to that same name, under two netnames built the same way: the bank's three initials, the word for a network, and a two-digit counter.
• Two blocks in one parent range share the higher counter; the third, in a different range, carries a counter two lower.
• The value between the two is absent here, which means it was assigned to a block this autonomous system does not announce.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• Netname counters are handed out per organisation, and routing is arranged per purpose. The two have nothing to do with each other, so a gap in the sequence is the normal case rather than a fault: the missing network exists, it is simply announced from somewhere else in the estate.
• Reading three consecutive counters as one system is the trap. The registry numbers what an organisation was given; the routing table shows how it chose to split that up afterwards.
• Four upstreams on a thousand addresses is redundancy sized for the consequence of being unreachable, not for the volume of traffic.
