AS14511 — POLAR-COMMUNICATIONS

AS14511 announces 4 IPv4 prefixes covering 12,288 addresses and 1 IPv6 prefixes.

About this network

Four blocks from two ranges, all four filed under one netname whose suffix counts to two.

What it's used for

• A rural telephone cooperative's internet network. 12,288 addresses across four IPv4 prefixes plus one IPv6 prefix, 2610:188::/32, with two observed BGP neighbours.

Notable

• Every block carries the netname POLARCOMM-BLK-2, registered to Polar Communications with a Network Operations Center contact.
• The blocks pair up: a /20 and a /21 from 66.231, and a /20 and a /21 from 216.196.
• Twelve addresses were queried for reverse DNS and none returned a name.

Interesting

• One netname on four blocks from two unrelated ranges means the registry record was reused rather than rewritten. The suffix implies a first block that no longer carries the label, so the numbering survives a history the current records no longer show.
• The pairing is the giveaway: each range holds a /20 and a /21, the shape of an initial request followed by a top-up that landed adjacent. Two ranges means it happened twice, years apart.
• No sampled address answered a reverse lookup. For a cooperative selling residential service that is a choice, since generated reverse names are cheap; leaving them off keeps subscriber addresses from being enumerated by walking the zone.
• The IPv6 allocation is a full /32 for a network of 12,288 IPv4 addresses. Every operator gets the same starting size, which flattens the difference between a co-op and a national carrier in one column of the routing table.
