About this network

TTC-CZ is operated by TTC Telekomunikace s.r.o., a Czech supplier of communication infrastructure solutions within the TTC Holding group.

What it's used for

• The address space carries infrastructure and teleport services, evidenced by netnames TTC-INFRASTRUCTURE and TTC-TELEPORT and reverse DNS entries like ttcas21net.ttc.cz.
• The AS announces 1536 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a focused internal or service-specific network rather than a large-scale transit or access provider.
• Traffic from this AS consists of corporate and infrastructure endpoints for TTC Holding's ICT subsidiaries, supporting their communication infrastructure and data centre operations.

Notable

• Registrants for both announced prefixes are listed as Abuse-C Role, which aligns with the announcer TTC Telekomunikace s.r.o.
• The address inventory is compact, consisting of two contiguous IPv4 blocks (46.226.18.0/23 and 46.226.20.0/22) and a single /32 IPv6 prefix, reflecting a tightly managed corporate estate.
