AS14299 — ADP1

AS14299 announces 33 IPv4 prefixes covering 33,280 addresses and 0 IPv6 prefixes.

About this network

One range cut into 33 announcements, every piece filed under the same netname, and not one address answers a reverse lookup.

What it's used for

• A payroll and human-resources company's own network. 33,280 addresses across 33 IPv4 prefixes, with five observed BGP neighbours and no IPv6 announced.

Notable

• All but one block sits inside 170.146, and every block that resolved carries the netname ADP-ESNET, registered to Automatic Data Processing, Inc.
• The exception is 24.104.148.0/23.
• The pieces run from /20 down to /24 and do not tile the range; large stretches of 170.146 are simply not announced.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Thirty-three announcements from five neighbours, all under one name. Nothing here is being advertised for traffic engineering between providers; the granularity is internal, and each piece most likely corresponds to a data centre or a business unit that was turned up on its own schedule.
• A network that answers no reverse lookups is a network with nothing on it meant to be reached by name from outside. Payroll processing is a business of inbound connections to a handful of published front doors, and everything behind them can stay unnamed.
• The gaps matter as much as the blocks. Holding a range and announcing half of it means the rest is either used privately or held in reserve, and the routing table cannot tell you which.
• One block from an unrelated range on an otherwise uniform estate is usually a later acquisition or a provider-assigned block at a single site.
