AS11731 AS11731 - Weston Solutions, Inc.

AS11731 belongs to Weston Solutions, Inc., an employee-owned environmental and infrastructure engineering and consulting firm headquartered in West Chester, Pennsylvania. It is a corporate enterprise network, not a service provider.

What it's used for

The AS carries Weston's own corporate connectivity. RIS sees just 2 IPv4 prefixes, 512 addresses, and 2 observed neighbours — the smallest useful shape a multihomed enterprise can have. Two upstreams and a pair of adjacent /24s is what a company buys an ASN for in the first place: it lets the same public addresses stay reachable when one circuit fails, without renumbering. There is no IPv6 in the RIS window.

The two prefixes, 162.43.197.0/24 and 162.43.198.0/24, are both registered in ARIN directly to Weston Solutions, Inc. Registrant and announcer are the same party, which rules out the IP-leasing shape entirely: nobody else's name is on this space.

Notable

The sampled reverse DNS resolves to *-static.hfc.comcastbusiness.net. That is worth reading carefully, because it is exactly the case where rDNS misleads. It does not mean the space is Comcast's; the RDAP registrant says otherwise. It means Weston's own ARIN blocks are riding Comcast Business circuits and wearing the upstream's default PTR template rather than a Weston-branded one. rDNS names the access path, never the holder.

Interesting

A firm with roughly a thousand professionals across two dozen offices needs far more addresses than 512 internally. That the public footprint is this small says the estate is overwhelmingly private space behind NAT, with only a thin edge exposed.
