About this network

MATHOST is operated by MatHost.eu, a Polish hosting and colocation provider.

What it's used for

• The address space carries hosting and colocation services, evidenced by reverse DNS entries like 89-144-32-64.epichost.pl and 89-144-32-127.mathost.eu, and netnames such as MATHOST and AMPRNET.
• The AS announces 768 IPv4 addresses and 11 IPv6 prefixes against 44 observed neighbours, a ratio consistent with a hosting or colocation provider rather than a transit or access network.
• Traffic from this AS consists of VPS instances, dedicated servers, game server hosting, and colocation hardware, as MatHost.eu explicitly provides these services in Poland.

Notable

• Registrants for the announced prefixes include Sebastian Stefanek trading as MatHost.eu, Amateur Radio Digital Communications, and GHOSTnet GmbH, with the primary registrant matching the AS holder.
• The address inventory includes a prefix registered to Amateur Radio Digital Communications (44.30.200.0/24), which does not align with the primary hosting business model.
