AS14010 — JACKHENRY

Network type: hosting

AS14010 announces 33 IPv4 prefixes covering 16,384 addresses and 0 IPv6 prefixes.

About this network

Thirty-five announcements, two netnames, and one of those netnames records the team that filed it rather than what it holds.

What it's used for

• A core banking software company's network. 16,640 addresses across 35 IPv4 prefixes, with 20 observed BGP neighbours and no IPv6 announced.

Notable

• Most blocks carry the netname JHA-1, registered to Jack Henry & Associates, Inc.
• Three carry JHA-NETENG1, on blocks from a different range.
• The space is cut very fine: /21 at the largest, then /22s, /23s and a long run of single /24s, nearly all from 52.128.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• NETENG is a network engineering group. Somebody registered a block under their own team's name, which happens when the request comes from operations rather than from whoever owns the addresses, and nobody ever corrects it.
• Thirty-five announcements from 16,640 addresses is roughly one route per /23. That granularity only makes sense if each piece is delivered somewhere different, which for a company processing transactions on behalf of banks means one route per institution or per data centre.
• Twenty neighbours is high for a network that publishes nothing. The company's customers reach it directly rather than across the open internet, and each of those arrangements is an adjacency.
• Publishing no reverse names and no IPv6 while announcing 35 prefixes is a network built to be connected to, not found.
