Summary
Universidade Catolica Portuguesa
education university legacy
The Universidade Católica Portuguesa (Catholic University of Portugal), a private university founded in 1967 with campuses in Lisbon, Porto, Braga and Viseu. The AS carries the university's own network.
What it's used for
- Campus connectivity, single-homed. The AS announces exactly one prefix,
158.162.124.0/22(about 1,000 addresses), and has a single BGP neighbour: it hangs off FCCN, Portugal's national research and education network. - The RIPE object for the prefix is registered directly to the university with the netname
UCP-LISBOA, co-maintained by FCCN — the standard arrangement for a Portuguese institution numbered out of the NREN's legacy space.
Notable
- Institutional space, not consumer space: a stub academic network with one upstream. rDNS for the block was not resolvable from outside at the time of writing, so the registry object rather than the naming is the evidence here.
- The prefix sits in a legacy
158.0.0.0/8allocation and carriesRIPE-NCC-LEGACY-MNT, marking it as pre-RIR address space that predates the modern allocation policy.
Interesting
- The university uses a fraction of what a public Portuguese university of the same size would announce. Private institutions in Europe often got a single small assignment through the NREN rather than a large early block of their own, and never had reason to grow it.

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.
