About this network

The AS handle HYPERLEAF1 is held by Hyperleaf, LLC.

What it's used for

• The address space is predominantly registered to Netrax, LLC under the netname NETRAX-CIDR, with one block registered to York Business Institute (YBI) and one to American Registry for Internet Numbers (NET23).
• The AS announces 5,632 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, with 6 observed neighbours. This ratio of address volume to peer count suggests a hosting or business network rather than a transit provider.
• Traffic from this AS consists of hosted services and business endpoints, given the corporate registrants and the lack of residential access indicators in the netnames.

Notable

• Registrants differ from the AS holder; most prefixes are registered to Netrax, LLC, indicating leased or acquired address space, while one prefix belongs to York Business Institute.
• The inventory is fragmented into multiple /23 and /24 blocks within the 207.181.128.0/17 range, alongside a single /23 in the 23.138.0.0/16 range.
