About this network

An autonomous system of Sony (ASN-SONY), now registered to Sony Pictures Technologies Inc. in Culver City, California.

What it's used for

• Corporate networking for Sony's US operations and the technology group behind Sony Pictures Entertainment — internal systems and company-facing services.

Notable

• Enterprise address space: it serves one media company's own infrastructure, not subscribers.
• The AS was registered in 1994 under Sony's US arm; the registry record was later moved to the Sony Pictures Technologies entity.

Interesting

• The registry handle is still the generic ASN-SONY from the 1990s, a good example of how a handle can outlive the exact corporate entity that first claimed it.
