Summary
Diallog Telecommunications
isp legacy
DIALLOGTORONTOCORE is Diallog Telecommunications, an independent Toronto ISP that resells home and business internet and phone service over the incumbent carriers' last mile. ARIN registers the ASN to Diallog at 2083 Danforth Avenue, Toronto, assigned in 2018.
What it's used for
RIS sees 9 IPv4 prefixes carrying 3,072 addresses, no IPv6, and 2 observed neighbours — a small access network with a couple of upstreams. That is the expected shape for a Canadian third-party internet access reseller: the subscriber last mile belongs to the incumbent, so the ISP needs only enough of its own space to number the customers it aggregates.
Notable
The prefix registrants look, at first glance, like the leased-address pattern: three different org names announcing from one AS. 207.167.88.0/22 registers to Surf Internet, the six 66.7.8x.0/24 blocks to Fastel Media Inc, and 23.130.32.0/24 to IAAK Technologies Inc. Checked properly, they are one corporate group, not unrelated third parties. The Surf Internet org record carries Diallog's own Danforth Avenue address and a support@diallog.com contact; Fastel Media is a Toronto-incorporated, CRTC-certified ISP that is itself a subsidiary of IAAK Technologies; and the same Richmond, British Columbia phone number appears on the contacts for all three. Every one of them is a findable, incorporated Canadian company with a retail internet business, which is what separates an intra-group registration history from a set of shells.
Read together, the inventory is one small independent ISP group's subscriber space, gathered under the AS number its Toronto operation announces from.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,851 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
