About this network

cloudinfrastack, s.r.o. (cloudinfrastack) — a small Prague-based hosting and cloud-infrastructure provider, registered at Tachovské náměstí in Praha 3.

What it's used for

• Server hosting out of a single Czech location. It announces one 185.120.68.0/22 allocation, registered directly to the company as CZ-CLOUDINFRASTACKCOM-20151007, and the rDNS on it is first-party: routers named r1.cz1.cloudinfrastack.com and xe-r1-r2.cz1.cloudinfrastack.com, with customer sites resolving to their own domains.
• Roughly 1,024 addresses in total, holding a few hundred hosted domains — the scale of a boutique provider, not a large cloud.

Notable

• Self-registered allocation plus first-party router rDNS is what separates a real small host from an address broker wearing the same silhouette. The inventory here is a single contiguous block with a coherent reverse zone.
• Peers widely for its size, taking transit from a couple of upstreams while exchanging traffic at Czech exchanges.

Interesting

• The low AS number is not an early-internet pedigree. The organisation object (May 2015), the /22 allocation (October 2015) and the AS assignment (October 2015) all date from the same year: AS8646 is a reissued number, and the netname even carries its allocation date, 20151007.
