About this network

CZ-AS is operated by AtNOC GmbH, an Austrian computing infrastructure and web hosting provider based in Vienna.

What it's used for

• The address space carries customer and service infrastructure, evidenced by reverse DNS entries like 095129205254.cust.akis.net and netnames such as AT-AKIS-20090223 and AT-AKIS-20140801.
• The AS announces 3584 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, while maintaining 35 observed neighbours; this ratio of modest address space against a significant number of peering partners suggests a role focused on hosting and business connectivity rather than large-scale residential access or pure transit.

Notable

• Registrants for the two largest prefixes are listed as A.K.I.S. GmbH, while the smallest prefix is registered to AtNOC GmbH, indicating a relationship between the two entities or historical address allocation.
• The address inventory is compact, consisting of three distinct IPv4 blocks and two IPv6 blocks, all located in Austria.
