PeeringDB records ten internet exchanges in Mumbai and 39 colocation facilities, with 994 exchange participants and 900 network presences across those facilities. DE-CIX Mumbai is the best connected by participant count at 449. An address that geolocates to Mumbai identifies the network that announces it and the location that network published, not a device standing in the city.

What a Mumbai IP address tells you
Ten exchanges appear in the Mumbai record, and three of them hold most of the participants. DE-CIX Mumbai reports 449, Extreme IX Mumbai 249 and NIXI Mumbai 179, while AMS-IX Mumbai has 69 and Equinix Mumbai 25. Five smaller exchanges account for 23 participants between them. Colocation carries weight of its own, with 900 network presences spread over 39 facilities, the biggest single counts being Equinix MB1 - Mumbai (GPX Mumbai 1) at 256 networks and Web Werks Mumbai 1 at 194. NIXI Mumbai is the one Mumbai exchange with a carrier ASN recorded against it, AS4637.
An address that geolocates to Mumbai is an address an operator chose to register in Mumbai. Networks announce blocks from a registry record, and that record carries a corporate or administrative address rather than the position of the equipment using the space. Indian mobile traffic reaches the internet through a small number of gateways, so a handset several states away can present an address whose published location reads Mumbai. Geolocation databases copy what the operator published, so a city label repeats the operator's paperwork instead of measuring the connection.
Anyone checking an address gets more from the origin ASN than from the city label. Look up the specific prefix, read its netname and the organisation attached to it, and see whether the announcing network is a mobile operator, a fixed-line provider or a hosting company sitting inside one of the Mumbai facilities. A network peering at DE-CIX Mumbai alongside 448 others behaves differently from one whose only presence is a single colocation cage. Mumbai is a routing answer, not a street address.
Questions
Which internet exchanges are in Mumbai?
PeeringDB lists ten. DE-CIX Mumbai is the biggest at 449 participants, followed by Extreme IX Mumbai at 249, NIXI Mumbai at 179, AMS-IX Mumbai at 69 and Equinix Mumbai at 25. WSNL-IX, X3M-IX, MX-IX Mumbai, Bharat IX - Mumbai and SP-iXP Mumbai each record fewer than ten participants.
Do India mobile carriers peer in Mumbai?
The registry attaches one carrier ASN, AS4637, to NIXI Mumbai, and none to the other nine Mumbai exchanges. No named mobile operator is tied to the city in this snapshot, so the honest answer is that PeeringDB does not record Indian mobile networks peering here beyond that single ASN.
Does an IP that geolocates to Mumbai mean the device is there?
No. It means the network announcing that block published Mumbai as its location, or a geolocation vendor inferred Mumbai from that record. Mobile addresses in particular are handed out from pools behind a few gateways, so the registered city and the physical device can be far apart.
