Summary
Columbia/UFMG PEERING Research Testbed
education research
A networking research testbed operated jointly by academics at Columbia University and the Universidade Federal de Minas Gerais (UFMG). PEERING gives researchers real BGP connectivity to experiment with internet routing.
What it's used for
- Allocating AS numbers and prefixes to researchers so they can announce routes and study real-world BGP behavior from a controlled testbed.
Notable
- An IP here is research infrastructure for internet-routing experiments, classified
educationrather than commercial hosting.
Interesting
- PEERING lets researchers safely originate and withdraw BGP prefixes from many vantage points, a capability normally reserved for network operators.

Classification and threat
Education University, school or national research and education network.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
