AS11328 BIO-RAD-ASN

BIO-RAD-ASN is held by Bio-Rad Laboratories, Inc., the Hercules, California maker of life-science research instruments and clinical diagnostics products. It is a small enterprise stub: RIS sees 2 IPv4 prefixes, 512 addresses, no IPv6, and 2 observed neighbours.

What it's used for

Bio-Rad's own corporate internet presence. The two announced blocks, 192.101.136.0/24 and 192.153.51.0/24, are registered in ARIN to Bio-Rad Laboratories under the handles NET1-BIO-RAD and NET2-BIO-RAD. Holder and registrant are the same company, with no third-party or provider-assigned space in the mix, so there is nothing here that looks like resold or leased addressing.

Notable

The role signal is unambiguous. Two BGP neighbours against 512 addresses is an enterprise that has bought transit from a couple of upstreams for redundancy. A network in the business of carrying other people's traffic — a hosting company or a regional carrier of comparable address size — would show peer counts an order of magnitude or two higher. Nothing about this AS is selling connectivity.

Interesting

The two /24s sit in the old class-C swamp (192.101.x, 192.153.x), which is consistent with a company that has held these blocks for a long time and never needed more: a diagnostics manufacturer runs its user estate on RFC 1918 space behind NAT and only needs public addresses for the edge — mail, VPN, remote access, a handful of public services.

We tag research alongside enterprise because of what Bio-Rad is — a life-science instrumentation firm whose customers are laboratories — but the network itself is a commercial corporate network, not an academic or NREN one, and it is classified as a business network accordingly. No PTRs were returned on the addresses we sampled, which tells us nothing either way; it is a sample, not a survey.
