About this network

3M-HDQ-AS is the corporate network of 3M Company, the diversified manufacturer headquartered in the Saint Paul, Minnesota area.

What it's used for

• Enterprise IT for 3M: corporate offices, manufacturing sites, laboratories and the company's internet-facing services.
• Announces a large legacy inventory — including 130.99.0.0/16, 136.229.0.0/16 and contiguous space in 169.6.0.0/15 and 169.8.0.0/14 — roughly a million IPv4 addresses in total.

Notable

• The address count is misleading as a measure of activity. Almost none of this space carries public reverse DNS, which is the signature of a corporation that numbered itself generously in the early 1990s and has kept the space internal ever since.
• Nothing here is eyeball or hosting space: it is a single company's private network, and prefixes should be attributed to 3M's own sites rather than to any service provider.

Interesting

• Large industrial firms that joined the internet early are among the quietest holders of big IPv4 blocks — visible in the routing table, nearly invisible in the DNS.
