AS11193 COMNET S.A.

AS11193 is held by Comnet S.A., an Argentine internet provider. Its address space sits in LACNIC's 200.61.0.0/20, and the AS appears in the customer AS-SET of Silica Networks Argentina, the Grupo Datco fibre carrier — so it is a downstream of that carrier rather than an independent transit network.

What it's used for

Business connectivity in Argentina. RIS observes 11 IPv4 prefixes and about 2,816 addresses, no IPv6, and a single BGP neighbour — every route leaves through one upstream. The prefixes are all /24s carved out of the same registered LACNIC range, which is a normal way for a small provider to slice a single allocation across customer sites.

The reverse DNS says what the space carries. Most sampled addresses answer with static-assignment names of the form ip-5-8-61-200.static.silicanetworks.com, and interleaved with them are customer-owned service records: mail.berkley.com.ar and smtp.winstar.net.ar. Static addressing plus customer mail servers is a business-access and small-hosting profile, not a consumer broadband pool.

Notable

The rDNS belongs to Silica Networks, not to Comnet — a reminder that reverse DNS names the party operating the zone, never the AS holder. A downstream network very often wears its upstream's default naming. It does not, on its own, establish that Comnet has been absorbed into the Silica/Datco group, and the routing evidence here cannot settle that either way.

The prefix registrant lookups returned only the LACNIC range boundaries rather than an organisation handle, so registrant identity is not independently confirmed from the pack.
