Lisbon · Portugal
PeeringDB records six exchanges in Lisbon, Portugal, with 155 participant records across them and 124 network presences in seven colocation facilities. DE-CIX Lisbon is the best connected by participant count, at 62. An IP address that geolocates to Lisbon shows where an operator registered the block, not where a device sits.
Internet exchanges in Lisbon
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.

What a Lisbon IP address tells you
Lisbon's routing weight sits in two exchanges. DE-CIX Lisbon carries 62 participants and GigaPIX - LAN 1 carries 56, with Equinix Lisbon at 18 and a second GigaPIX LAN at 17. LIS-IX has two participants and BGP.Exchange - Lisbon has none recorded. Colocation carries a comparable load, with 124 network presences across seven facilities, 83 of them at Equinix LS1 alone, ahead of FCCN Lisbon - SE06 and MEO LDV at 11 each. The carrier registry lists no Portuguese mobile operators, though one carrier ASN, AS2686, peers at DE-CIX Lisbon.
An address that geolocates to Lisbon may not be attached to anything in Lisbon. An operator announces a block from a registry record, and that record names one address for the whole allocation, often a head office rather than the site where the traffic starts. Mobile networks compound this, because handset traffic leaves through a small number of gateways that can sit in another city. Geolocation databases read the operator's own published location, so they repeat what the operator wrote, at whatever precision the operator chose.
Someone checking a Lisbon address should read the origin ASN and the netname on the specific prefix rather than the city label. The origin ASN says which network announces the block, and the netname and registry record say who holds it and how the holder described it. Setting that against the 155 participant records and 124 facility presences PeeringDB lists for Lisbon shows whether the announcing network has any recorded presence in the city at all.
Questions
Which internet exchanges are in Lisbon?
PeeringDB lists six exchanges in Lisbon. DE-CIX Lisbon has 62 participants and GigaPIX - LAN 1 has 56. Equinix Lisbon has 18, GigaPIX - LAN 2 has 17, LIS-IX has 2, and BGP.Exchange - Lisbon has no participants recorded.
Do Portugal mobile carriers peer in Lisbon?
The carrier registry used here lists no mobile operators for Portugal, so the data cannot answer that. PeeringDB does record one carrier ASN, AS2686, among the 62 participants at DE-CIX Lisbon. Peering at an exchange is also separate from where a carrier's mobile gateways sit.
Does an IP that geolocates to Lisbon mean the device is there?
No. The city label comes from the operator's registry entry for the address block, which can name a head office or a national allocation rather than one site. Check the origin ASN and the netname on the prefix before treating the label as the device's location.
