About this network

The corporate network of KPMG LLP, the US member firm of the KPMG audit, tax and advisory network, operating under the handle KPMGL-AS and administered from KPMG's Montvale, New Jersey offices.

What it's used for

• Enterprise connectivity for a large professional-services firm: office and client-site access, internal applications, and the firm's public-facing services.

Notable

• It announces dozens of prefixes drawn from a contiguous legacy allocation in 199.206.0.0/16 and 199.207.0.0/16, including a /18 and several /20s. That block of space, held by a single accounting firm, is a hallmark of a mid-1990s enterprise registration made before addresses were scarce.
• The ARIN contacts are an Information Security Group, a Network Operations Group and a Security Operations Group, which is exactly what you would expect of an audit firm's own network rather than a service provider's.

Interesting

• The ASN sits in a run of sequential ARIN registrations from October 1996, alongside neighbours such as AS7233 and AS7234.
