AS20804 — ASN-TELENERGO Exatel S.A.

AS20804 announces 195 IPv4 prefixes covering 155,392 addresses and 14 IPv6 prefixes.

About this network

The AS handle ASN-TELENERGO is held by Exatel S.A., a major Polish telecommunications operator.

What it's used for

• The address space carries residential and business customer traffic, evidenced by reverse DNS entries such as ip-213-172-183-254.unregistered.net.exatel.pl and host4-254.chomiczowka.waw.pl.
• With 155,648 IPv4 addresses announced across 197 prefixes and 505 observed neighbours, the high neighbour count relative to the address inventory indicates a role focused on transit and peering rather than a purely isolated access network.

Notable

• All sampled registrants are listed as Exatel S.A., which aligns directly with the current announcer identity.
• Exatel was acquired by Orange Polska in 2014, leading to the integration of its network infrastructure into the Orange brand, though the AS number and registry records retain the historical Exatel designation.
• The inventory includes a mix of /19, /20, and /21 prefixes, with the largest blocks being 88.220.0.0/19 and 213.172.160.0/19, reflecting a legacy allocation structure from the TeleNergo era.
