AS14979 AERONET-WIRELESS

Seven different netnames for one company on twelve blocks, and 29 BGP neighbours on a network of 24,064 addresses.

What it's used for

• A wireless broadband provider serving Puerto Rico. 24,064 addresses across 24 IPv4 prefixes plus two IPv6 prefixes, with 29 observed BGP neighbours.

Notable

• Every block that resolved is registered to Aeronet Wireless, but under netnames that never settle: AERONET-CGNT-NET-1, AERONE-2, AERONET-WIRELESS, AERONET-PUBLIC, AERONET-BROADBAND, AERONETPUBLICRANGE and plain AERONET.
• The IPv6 announcements are a /32, 2606:d6c0::/32, and a /48, 2001:470:13e::/48, from unrelated ranges.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• The IPv4 space arrives in more than a dozen separate ranges, from /20s down to eight /24s.

Interesting

• Twenty-nine neighbours is more than most networks ten times this size manage. An island operator has one expensive way off the island and every incentive to buy from everyone, so redundancy shows up as adjacencies rather than as address space.
• Seven netnames for one registrant is what happens when each acquisition is filed by whoever handled it. One drops a letter, one runs the words together, two describe the service instead of the company.
• Two of those netnames say public, which in a wireless network usually distinguishes routable customer space from the private addressing behind the radios.
• Announcing a /48 alongside a /32 means one of the two came from somewhere other than the registry allocation, and it is the smaller one carrying the exception.
