AS11267 PEIRCE-PHELPS

PEIRCE-PHELPS belongs to Peirce-Phelps, Inc., the Philadelphia HVAC distributor founded in 1926. It supplies Carrier residential and commercial heating and cooling equipment, parts and supplies to thousands of contractors from branches across Pennsylvania, New Jersey and Delaware. Watsco acquired the HVAC business in 2019, and it now operates as a subsidiary of Carrier Enterprise.

What it's used for

This is a corporate enterprise edge, nothing more. RIS observes one IPv4 prefix, 198.181.161.0/24, carrying 256 addresses, no IPv6, and two observed neighbours. Two neighbours is the signature of a company multihoming for resilience across a pair of transit providers. A distributor with branch warehouses does not sell connectivity, and the routing shows no sign that it does.

The /24 is registered to PEIRCEPHELPS, org Peirce-Phelps, Inc. — the holder announces its own ARIN-held space, with no third-party registrant anywhere in the inventory. Self-registered space announced by its own registrant is the cleanest possible first-party signal, and it rules out the IP-leasing shape entirely.

What a single /24 carries for a company like this is a small internet-facing estate: mail, VPN termination for branches and field staff, remote access for the ordering and inventory systems, and whatever web presence is not outsourced. The branch network itself would ride private WAN or provider-assigned circuits, not this public block.

Notable

The AS survived a change of ownership. Watsco's 2019 acquisition folded the business into Carrier Enterprise, but the ARIN org record and the announcement still carry the Peirce-Phelps name — the network kept its identity even though the corporate parent changed. That is common and it is why the holder name on an ASN is a statement about registry paperwork, not about who signs the cheques.

Interesting

The company name is old enough that it long predates the internet. Peirce-Phelps has been distributing heating equipment in Philadelphia since 1926, and the AS is simply how a business of that age reaches the network today.
