About this network

The AS handle CZTTNET-AS is held by TTNET s.r.o., a Czech internet service provider.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries like core.ttnet.cz and netnames such as TTN-FREENET2 and TTN-INFRASDL-NET128.
• The network announces 13,312 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

• All registrants in the evidence pack are consistent with the announcer, listing either TTNET s.r.o. or CZTTNET ABUSE for the largest prefixes.
• The address inventory is finely subdivided into multiple /20, /21, /22, and /23 blocks, suggesting internal segmentation for different service tiers or geographic sites within the Czech Republic.
