About this network

NEPTUNE-NETWORKS is the AS handle for Neptune Networks, LLC.

What it's used for

• The address space carries business and enterprise traffic, evidenced by the netnames NEPTUNE-NETWORKS-V4-01 through V4-04 and a single reverse DNS record pointing to pfr1.playfulrewardsapp.com.
• With 2,816 IPv4 addresses announced across 7 prefixes and 196 observed neighbours, the high neighbour-to-address ratio indicates a transit or network service provider role rather than an access network.

Notable

• Registrants for the largest prefixes (209.151.100.0/22, 172.82.22.0/23, 23.157.160.0/24) align with the announcer, Neptune Networks, LLC, while smaller prefixes are registered to Private Customer.
• The address inventory is mixed, comprising three large blocks under the Neptune Networks netname and four smaller /24 blocks registered to private customers, suggesting a combination of owned infrastructure and leased or customer-specific space.
