Delhi · India
PeeringDB records seven internet exchanges in Delhi carrying 442 participants between them, alongside six colocation facilities holding 100 network presences. Extreme IX Delhi is the best connected at 176 participants, ahead of NIXI Delhi at 115 and DE-CIX Delhi at 104. A Delhi geolocation result describes where an operator registered an address block, not where a device sits.
Internet exchanges in Delhi
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.

Buildings where networks put equipment. The network count is how many PeeringDB members list a presence there, which shows where capacity in the city sits.

What a Delhi IP address tells you
Delhi's recorded capacity sits in exchanges rather than in colocation. The seven exchanges carry 442 participants, while the six facilities hold 100 network presences between them, the biggest being STT Delhi 2 at 41 networks and STT Delhi 1 at 24. Extreme IX Delhi has the most members at 176, then NIXI Delhi with 115 and DE-CIX Delhi with 104. ANI-IX Delhi has 30, MX-IX Delhi nine and Insta-IX Delhi eight, and IPNET-DELHI is listed with none. NIXI Delhi is the only Delhi exchange with a carrier ASN attached, AS4637.
An address that geolocates to Delhi is an address whose operator published Delhi in the registry record for that block. The record describes the organisation, not the handset or server using the space. Indian mobile networks aggregate subscriber traffic into a small set of gateways, so an address stamped Delhi can front a connection from anywhere the operator runs radio. Geolocation databases take the operator's published location as their input, which means they repeat the registration rather than locate the endpoint.
The origin ASN is the field worth reading. Check which network announces the exact prefix, look at the netname and the registered organisation, and ask whether that network is a mobile operator or a hosting provider inside one of the six Delhi facilities. Delhi's imbalance helps here, since a city with 442 exchange participants and only 100 facility networks is more about interconnection than about servers on the ground. The city string alone settles nothing.
Questions
Which internet exchanges are in Delhi?
Seven. Extreme IX Delhi has 176 participants, NIXI Delhi 115, DE-CIX Delhi 104 and ANI-IX Delhi 30, with MX-IX Delhi at nine and Insta-IX Delhi at eight. IPNET-DELHI is listed in PeeringDB with no participants recorded.
Do India mobile carriers peer in Delhi?
The registry attaches one carrier ASN, AS4637, to NIXI Delhi and none to the other six exchanges. Beyond that ASN, PeeringDB does not tie named Indian mobile operators to Delhi exchanges in this snapshot, so nothing more can be claimed from the data.
Does an IP that geolocates to Delhi mean the device is there?
No. It shows that the network announcing the block published Delhi, or that a geolocation vendor inferred Delhi from that publication. Mobile addresses are assigned from operator pools that reach far beyond the registered city, so the label and the device can disagree.
