AS15566 — INFOTECHNA Budapest

Network type: residential

AS15566 announces 1 IPv4 prefixes covering 1,024 addresses and 1 IPv6 prefixes.

About this network

The one address that answers is a certificate probe, named as such.

What it's used for

• A small provider. One IPv4 /22 and one IPv6 /32 announced from Hungary, a thousand addresses, across nine observed BGP neighbours.

Notable

• The single answering address names a certificate probe under the company's own domain, so the one public name in this network belongs to a monitoring host.
• The AS handle continues past the company code into a city name.
• The one IPv4 block carries the country code, the company and an allocation date, with the company and an abuse role as registrants.
• The IPv6 prefix is far larger than the IPv4 holding, which is ordinary, since scarcity does not apply on that side.
• Three addresses were queried for reverse DNS and one returned a name.

Interesting

• Nine neighbours for a thousand addresses is unusually dense. Most networks this size have one or two, and the difference means traffic here reaches many places directly.
• A probe host is a small disclosure. It says the operator watches certificate validity, and it tells anyone interested exactly which address does the watching.
• A /32 of IPv6 against a /22 of IPv4 is the standard modern pairing, and holding both under one small AS number is what independence from any single provider costs now.
