About this network

Nearly half a million consumer addresses in Chile, and not one of them answers to a name.

What it's used for

• A regional telecom operator's network. 475,904 addresses across 193 IPv4 prefixes plus 27 IPv6 prefixes, with 12 observed BGP neighbours.

Notable

• All 220 announced prefixes are attributed to Chile.
• Netnames are the address ranges themselves, and several announced prefixes share one: 179.56.0.0/18, 179.57.64.0/18, 179.56.96.0/19, 179.56.224.0/19, 179.57.128.0/19 and 179.57.192.0/19 all fall under 179.56.0.0 - 179.57.255.255.
• Every registrant field reads Telefonica del Sur S.A., with no subsidiary or city breakdown.
• The IPv6 announcement runs 2803:6f00::/46, two /47s, then /45, /44, /43, /42, /41, /40 and /39.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• The registry lookups for 179.56.0.0/18 and 179.57.32.0/19 failed.

Interesting

• Six announced prefixes covering one registered range is deaggregation: the space was allocated once and is advertised in pieces so different parts can take different paths. The registry sees one allocation; the routing table sees six.
• An access network this size with nothing answering a reverse lookup is the exception among its peers. Most consumer ISPs publish a name per address, encoding the city, the access technology or whether the line is fixed. This one publishes nothing, so an address here carries no information beyond the prefix it sits in.
• The IPv6 ladder doubling at every step is the arithmetic of a range whose size is not a power of two, not a design decision.
