probe-br.a1noc.com

A monitoring probe of a1noc in São Paulo, Brazil.

What this server does. It runs uptime and network checks that a1noc customers set up for their own websites, servers and domains: ping, TCP and UDP port checks, HTTP(S), DNS, TLS certificates, mail servers, traceroute and similar.

If you see it in your logs, someone who runs a service on your network or domain is most likely monitoring it with a1noc. Checks run at a fixed, low rate (typically once a minute or less). They are never load tests, port scans of whole networks or exploit attempts, and private or reserved addresses are always refused.
