AS11787 PACOURTS-AS

PACOURTS-AS is the network of the Supreme Court of Pennsylvania — in practice the Administrative Office of Pennsylvania Courts, whose ARIN address is 5035 Ritter Road, Mechanicsburg, Pennsylvania. It is a genuine state-judiciary network, held by the court itself since ARIN registered the AS in 1998.

What it's used for

This is the Pennsylvania Unified Judicial System's internet edge, not a service provider. RIS observes 4 IPv4 prefixes totalling 1,024 addresses and no IPv6, reaching the internet through only 2 observed neighbours — four adjacent /24s and a pair of upstreams, which is exactly the shape of a single-purpose government agency network with redundant transit and nothing to resell.

All four /24s are registered in ARIN directly to the Supreme Court of Pennsylvania, under two of the court's own network handles, so the announced inventory and the legal holder line up with no third-party space in between. The court system runs statewide judicial applications from here — the docket and case-management systems that the Pennsylvania courts publish to attorneys and the public, plus the connectivity that ties county courthouses and district magistrate offices back to central IT.

Notable

A judiciary-branch AS is unusual: most US state government routing sits behind a single executive-branch or state-IT autonomous system, but Pennsylvania's courts are administratively separate and run their own. Two of the four /24s carry a distinct PACOURTS-VRI network handle, suggesting a segregated block for a specific court service rather than general office space.
