About this network

AS28103 is operated by TEISA (Tecnología en Electronica e Informatica S.A.), a regional internet service provider in Paraguay.

What it's used for

• The address space carries customer-facing infrastructure, evidenced by reverse DNS entries such as mx.rolesa.com.py and multiple host.teisa.com.py records.
• The AS announces 8192 IPv4 addresses across 11 prefixes and 1 IPv6 prefix, with 15 observed neighbours. This ratio of address space to peering partners is consistent with an access or eyeball network serving local subscribers rather than a transit provider.

Notable

• All RDAP registrants for the announced prefixes match the AS holder, TECNOLOGIA EN ELECTRONICA E INFORMATICA SOCIEDAD ANONIMA (T.E.I.S.A), confirming direct ownership of the inventory.
• The address inventory is fragmented into multiple /22, /23, and /24 blocks across different ranges (e.g., 201.222.48.0/21, 131.161.252.0/22, 190.110.226.0/23), suggesting historical accumulation of space rather than a single contiguous allocation.
