About this network

Corporate network of GlaxoSmithKline (GLAXOSMITHKLINE), the global pharmaceutical company, registered through ARIN at its US offices in Philadelphia, Pennsylvania.

What it's used for

• Enterprise networking for GSK's own sites — offices, research facilities, and internal systems.
• About 1,000 IPv4 addresses, an enterprise-sized footprint rather than a provider one.

Notable

• This is a corporate network: traffic from this range is a pharmaceutical company's employees and infrastructure, not consumers.
• The ASN was registered with ARIN in 1994, under a name that only came into existence in 2000 when Glaxo Wellcome merged with SmithKline Beecham — the registry record was clearly renamed as the corporate identity changed beneath it.
