Summary
Embry-Riddle Aeronautical University
education university research legacy
NET-ERAU-PRC is Embry-Riddle Aeronautical University, the aviation and aerospace university with residential campuses in Daytona Beach, Florida and Prescott, Arizona (the PRC in the handle is Prescott's airport code). The AS carries the university's own campus space.
What it's used for
- University connectivity across the two residential campuses: student and staff networks, departmental and research systems, and the central services behind them.
- RIS sees 15 IPv4 prefixes / 67,840 addresses and 4 observed neighbours. Tens of thousands of addresses reached through a handful of upstreams is the institutional pattern — a lot of space, very little peering. No IPv6 is announced.
Notable
- The bulk of the space is
155.31.0.0/16, registered to Embry-Riddle Aeronautical University asERAU-FLORIDA, with/17,/21and/23more-specifics of it also announced. The Arizona side shows up separately as198.60.3.0/24under theERAU-AZ3handle. One legal entity, two campuses, one AS. - One prefix,
199.104.253.0/24, is registered to The University of Arizona under the handleUOAZ-Z. This looks like a third-party registrant but is not a leasing tell: the trailing-Zmarks an ARIN legacy-cleanup handle, and the registrant is a neighbouring public university — the residue of how the Prescott campus was historically connected, not an unrelated shell. Every other identified registrant is Embry-Riddle itself. - Several further
/24s (204.75.207.0/24, the206.207.15x.0/24run,192.101.135.0/24) round out the inventory; they are consistent with an institution that accumulated small legacy blocks over decades.
Interesting
- The handle names only the Prescott campus, but the address space is overwhelmingly the Florida block. Reading the AS from its handle alone would put the network in Arizona and miss where nearly all of it actually lives.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
