Mobile carrier
AS6167 is the autonomous system number (ASN) announced by Verizon Business. It announces 5,318 prefixes, 18,045,924 IPv4 addresses in total. Every address inside those ranges is routed by this operator, which is what makes the number the shortest answer to who runs a given address.
| Organisation | Verizon Business |
|---|---|
| Autonomous system | AS6167 |
| Network type | Mobile carrier |
| IPv4 prefixes | 991 |
| IPv6 prefixes | 4,327 |
| IPv4 addresses | 18,045,924Summed across every announced prefix. IPv6 is not counted; the numbers are meaningless at that scale. |
| In known VPN ranges | 0 of 991 prefixes |
| In known datacenter ranges | 0 of 991 prefixes |
The last two rows are a second opinion, counted against the X4BNet VPN and datacenter range lists rather than read off the operator name. A network with most of its prefixes in the VPN list is carrying anonymised traffic whatever it calls itself.
The largest ranges Verizon Business announces, biggest first. These are a sample and not the full routing table: 5,318 prefixes do not fit on a page, and the ones worth showing are the ones most traffic comes from.

Live check
The field is prefilled with 63.40.0.1, the first address of the largest range above. Change it for one from your own logs and you get the network, the operator and the verdict for that specific address.
Addresses on Verizon Business are mobile: phones and tablets behind carrier NAT. Our engine classifies them residential, with one caveat worth knowing. Carrier NAT puts thousands of subscribers behind one address, so an IP-level block here reaches far more people than intended, and rate limits keyed on the address will punish an entire city. Geolocation is coarse for the same reason.
The verdict for a single address is never settled by the ASN alone. It is the starting point, and IP Detection adds range membership, behaviour and history on top of it before it answers.
