About this network

A legacy PSINet Europe autonomous system (PSINet-Europe), now held by GTT Communications, one of the large global IP transit carriers.

What it's used for

• Carrying what remains of the PSINet Europe and VIA NET.WORKS estate inside GTT's network. The bulk of GTT's transit is announced from its main ASN, so 3291 today is a small, mostly historical remnant.

Notable

• The registry description still records the merge of the PSINet part (AS3291) and the VIA part (AS5669) of the same company, a fossil of a 2000s-era consolidation preserved in the RIPE database.

Interesting

• PSINet was one of the first commercial ISPs in the world and collapsed spectacularly in the dot-com bust; its European arm was sold on and eventually wound up inside GTT, which is why a founding-era brand still labels this ASN.
