AS11440 NETSVILLE

NETSVILLE is the autonomous system of Netsville, Inc., a small web-hosting and internet-property management firm based in Rochester, New York. It announces a single /20 and a single IPv6 /32.

What it's used for

RIS shows one IPv4 prefix, 69.55.64.0/20 (4,096 addresses), and one IPv6 prefix, 2606:c380::/32, with two observed neighbours. The IPv4 block is registered in ARIN to Netsville, Inc. itself under the handle NTVL: first-party space, no third-party registrant, nothing leased in.

Reverse DNS is delegated to the operator and the one sampled address resolves to roc-core5.netsville.com — a core router in Rochester, named in the company's own zone. That confirms two things: the rDNS is under Netsville's control rather than an upstream's default, and the block is being run as an operator's own estate. Netsville describes its work as managing large, complex web properties for clients, so the /20 is best read as hosting space: customer sites and the servers behind them, addressed out of one contiguous provider block.

Notable

Two neighbours means two upstream transit providers and no customer cone worth the name. This is a hosting shop with a redundant edge, not a carrier: a wholesale network of any scale would show hundreds of adjacencies against this address count, and it shows two.

Interesting

A /20 plus a full IPv6 /32 is a slightly lopsided pair — the v6 allocation could address vastly more than the v4 block ever will. That asymmetry is normal and reflects RIR policy rather than ambition: IPv6 /32s are the standard minimum allocation for an operator of any size, so even a small hosting company ends up holding one.
