About this network
Registered as CDM — CDM On-Line, doing business as Primary Network — of St. Louis, Missouri. The same Borman Drive address is today a Hostirian data centre, Primary Network's hosting business having become Hostirian.
What it's used for
- Web hosting, virtual servers, and colocation. Reverse DNS across its prefixes resolves to primarynetwork.com, hostirian.com, and customer hosting brands — the signature of a hosting provider, not an eyeball ISP.
- It announces a long tail of small prefixes, mostly /24s, consistent with hosting customers spread over legacy blocks.
Notable
- Primary Network began hosting websites in 1995, and the hosting arm was spun out under the Hostirian name in 2001; the ASN and its registrant record still carry the original CDM name.
- The ARIN record dates to April 1996, within the sequential run of assignments covering the mid-6400s.
