What a Porto Alegre IP address tells you
IX.br (PTT.br) Porto Alegre is the only exchange PeeringDB records in the city and accounts for all 246 of its peer connections. Colocation is spread rather than concentrated. The 16 facilities hold 116 network presences between them, and the busiest, BR.Digital Porto Alegre (PAE1), lists only 35 networks, with Adylnet Telecom - Porto Alegre and PIX Nossa Telecom PAE at 14 each and Cirion Porto Alegre at 13. None of Brazil's mobile ASNs, Claro's 22085, TIM's 26615 or Vivo's 26599 and 27699, appears in the exchange record.
An address that geolocates to Porto Alegre may not be a device in Porto Alegre. The city in a lookup comes from the record an operator filed for the address block, and that record holds one administrative address no matter how widely the block is used. Mobile networks route subscriber sessions out through a limited number of gateways, so a connection made elsewhere in the south can carry an address registered to a different city. Databases follow the operator's published location because it is the only location they have.
For an address in Porto Alegre, the origin ASN and the netname on the specific prefix are what to read. The ASN identifies the network announcing the block, which separates carrier mobile traffic from a fixed-line service or a machine hosted in one of the 16 facilities. Membership of IX.br (PTT.br) Porto Alegre describes how a network exchanges traffic with the other 245 participants, and nothing about the physical position of whoever uses an address.

Questions
Which internet exchanges are in Porto Alegre?
One. IX.br (PTT.br) Porto Alegre has 246 participants and accounts for every peer connection PeeringDB records in the city. Alongside it, 16 facilities hold 116 network presences, headed by BR.Digital Porto Alegre (PAE1) with 35 networks.
Do Brazilian mobile carriers peer in Porto Alegre?
The exchange record does not list them. Claro's ASN 22085, TIM's 26615 and Vivo's 26599 and 27699 are absent from IX.br (PTT.br) Porto Alegre in this data. Private interconnection inside the city's facilities would not appear in PeeringDB either way.
Does an IP that geolocates to Porto Alegre mean the device is there?
No. The city comes from the registry entry for the address block, which reflects the operator's administrative address rather than any measurement. On mobile blocks the gap can be wide. Read the origin ASN and the netname on the prefix.
