About this network

AS-BENESTRA is held by SWAN, a.s. of Bratislava, Slovakia's largest domestically owned alternative telecoms operator. Benestra merged into SWAN in the late 2010s, and SWAN later absorbed the mobile operator 4ka.

What it's used for

• Fixed connectivity, data services and internet access, historically weighted toward corporate and public-sector customers, which is the segment Benestra was built around and which SWAN still serves under its own brand.
• Consumer fixed and mobile services sit under the 4ka brand within the same group, so the AS carries a mix rather than a purely business estate.

Notable

• The Benestra name survived a long chain of ownership changes in the Slovak alternative-operator market before landing at SWAN; the AS handle is the last visible trace of it.
• With a few hundred thousand addresses, this is one of the larger non-incumbent networks in Slovakia.
