About this network

AS27813 is operated by Teledifusora S.A., a major Argentine cable television and internet service provider.

What it's used for

• The address space carries residential and business internet traffic, evidenced by reverse DNS entries pointing to express.com.ar (e.g., 254.87.51.38.stacm.express.com.ar, 254.119.2.190.ros.express.com.ar).
• With 38,912 IPv4 addresses announced across 26 prefixes and only 4 observed neighbours, the high address-to-neighbour ratio indicates an access/eyeball network rather than a transit provider.

Notable

• Registrants for the majority of prefixes are Teledifusora S.A., with netnames such as TELEDIFUSORA-CGNT-NET-1 and TESA-CGNT-NET-1; one prefix (138.186.212.0/22) is registered to G2K ARGENTINA S.A..
• The inventory is finely subdivided into many /22 and /24 blocks, consistent with site-by-site segmentation for a large cable operator.
• The AS has been observed in routing tables since 2006.
