Summary
MitoTec
isp enterprise legacy
IBX-CHICAGO is MitoTec, a Chicago-area business ISP and managed IT provider registered to ARIN org CONVE-48 at Burr Ridge, Illinois. It is part of the ConVergence Technologies family of companies and sells internet access, VoIP, managed networking and Wi-Fi to businesses in the western Chicago suburbs.
What it's used for
Business connectivity and managed services, not consumer broadband and not transit. RIS sees 8 IPv4 prefixes (4,352 addresses), one IPv6 /32 at 2606:7380::/32, and only 3 observed BGP neighbours. A handful of neighbours against a few thousand addresses is an end-network-plus-customers shape: MitoTec buys transit from a small number of upstreams and announces its own space plus the space of the customers it serves. One prefix carries the netname ORDWISPSOUTH, which reads as a fixed-wireless segment on the south side of the Chicago metro.
Notable
The prefix registrants look scattered at first glance and are not. Most blocks register to MitoTec under the netname IVN-OAKIL — IVN is InVision Networks, a sibling brand whose domain still serves as the AS's abuse contact. The two apparent outsiders are ordinary carrier reassignments: 208.78.192.0/21 registers to Florida Automotive Distributors, and ARIN records it as a customer assignment with MitoTec as the administrative and technical contact. A second block sits with Trimega on the same pattern. Customer SWIPs under a provider's own AS are exactly what a small business ISP should look like.
Interesting
The handle suggests a Chicago interconnect, but the AS is an access and managed-services network, not an exchange point.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-24, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,779 prefixes, as published 2026-10-25. 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.
