About this network

AS27751 is operated by Neunet S.A., a regional internet service provider in Argentina.

What it's used for

• The address space carries residential broadband access, with reverse DNS entries explicitly identifying xdsl and ftth (fiber-to-the-home) endpoints, such as xdsl255-239-centenario.neunet.com.ar and ftth-255-169-centenario.ctc8309.com.ar.
• The network announces 21,504 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining only 6 observed routing neighbours; this high address-to-neighbour ratio indicates an access network rather than a transit provider.

Notable

• Registrants for the largest prefixes are unavailable due to fetch failures, but the available registrant for 190.121.176.0/20 is Neunet S.A., matching the AS holder.
• The prefix 179.49.168.0/22 is registered to COOPERATIVA DE PROVISION DE SERVICIOS TELEFONICOS Y OTROS SERVICIOS PUBLICOS Y COMUNITARIOS DE CENTENARIO LIMITADA, a cooperative entity whose reverse DNS (ctc8309.com.ar) aligns with the Neunet/CTC branding.
• The inventory consists of four distinct IPv4 blocks, including two /19s and one /20, alongside a single /32 IPv6 prefix.
