About this network

The AS handle CLEARFLY is operated by Clearfly Communications.

What it's used for

• The address space carries residential and business internet access, evidenced by netnames such as CLEARFLY-NB-1 through CLEARFLY-NB-4 and reverse DNS entries following the pattern as27400.net.
• The AS announces 7168 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 16 observed neighbours; this ratio of address space to peering partners is consistent with an access network provider rather than a transit carrier.

Notable

• All registrants for the announced prefixes are listed as Clearfly Communications, aligning perfectly with the AS holder.
• Secondary sources identify the operator as also known as Greenfly Networks, Inc., indicating a corporate rename or rebranding history.
• The inventory consists of four distinct IPv4 blocks, including /21s and a /22, alongside a single /32 IPv6 prefix, representing a consolidated but modest address estate for a regional ISP.
