What does a Bell Canada IP mean in a privacy test?
A Bell address as your visible IP means the connection left over a Bell line with no tunnel in the path. It is easier to place than most: Bell's hostnames carry a code for the serving exchange, so a Bell address can be pinned to a city by reading the PTR record rather than by trusting whatever a geolocation database guessed.
Where to get Bell Canada's address list
Bell publishes no allowlist, so the registry is the source. ARIN holds AS577 under the AS name BACOM, registered to Bell Canada on 3 March 1999, and the prefixes above are the largest currently announced. The AS577 page carries the registry record with the routing detail.
The two address families are not in the same state on this network, which matters if you are building a rule from either. AS577 announces over fifteen hundred IPv4 prefixes and fewer than a hundred IPv6 ones, so an IPv4 list of Bell is long, specific and needs maintaining, while the IPv6 side is a handful of aggregates that will cover far more of the network per line of configuration. A filter that only enumerates IPv4 will increasingly miss Bell traffic, and one that only enumerates IPv6 has much less registry granularity to work with.
Reading a bell.ca hostname
Bell names addresses in the North American telephone-company style, and the result carries a location. 67.71.0.1 answers as toroon4322w-grc-01-67-71-0-1.dsl.bell.ca: a six-character place code that reads as Toronto, Ontario, then an equipment identifier, then the address in dashes, then a zone naming the access technology. That is a statement about which facility serves the line, published by the operator, and it is more trustworthy than a commercial geolocation guess at the same address.
It is still a statement about the facility rather than about a person. A serving exchange covers a wide area, the code does not move when a laptop does, and nothing in it identifies a subscriber. The other thing it settles is what the address is not: AS577 is access network, so there is no rented compute here for a proxy or a VPN exit to sit on, and an address on it is a line rather than a machine.

Frequently asked questions
What IP ranges does Bell Canada use?
Bell announces its address space under AS577, which ARIN registers to Bell Canada under the AS name BACOM. The largest blocks currently routed there are listed above, including 67.71.0.0/16 and 142.186.0.0/16. Bell publishes no allowlist, so the ARIN record and the routing table are the sources that can be checked.
Why does a Bell Canada IP appear in my privacy test?
A Bell address as your visible IP means the connection left over a Bell line with no tunnel in the path. It is easier to place than most: Bell's hostnames carry a code for the serving exchange, so a Bell address can be pinned to a city by reading the PTR record rather than by trusting whatever a geolocation database guessed.
What does toroon mean in a bell.ca hostname?
It is a place code in the North American telephone-company style, and it reads as Toronto, Ontario. A full Bell hostname looks like toroon4322w-grc-01-67-71-0-1.dsl.bell.ca: place code, equipment identifier, the address in dashes, then the zone. It names the serving facility, not the customer.
Can I tell where a Bell IP address is from the hostname?
To the serving exchange, yes, and that is usually better than a commercial geolocation lookup because Bell publishes it. What it will not give you is a street or a subscriber - an exchange covers a wide area, and the code stays put when the person does not.
Does Bell publish a list of its IP ranges?
No. An allowlist exists so other networks can admit a service's servers, and Bell's addresses belong to its customers instead. The ARIN record for AS577 and the prefixes announced under it are the checkable list, and this site's AS577 page carries them.
