Summary
Southern Crossroads (SoX) — Georgia Institute of Technology
SOUTHERN-CROSSROADS-SOX is registered to the Georgia Institute of Technology, which manages and operates Southern Crossroads (SoX) — the Internet2 regional GigaPoP for the southeastern United States, serving the region's research-and-education community since 1997.
What it's used for
SoX is an aggregation point, not a destination network. Universities, K-12 systems, federal labs and non-profit research institutions across the Southeast connect into it, and SoX hands their traffic onward to Internet2, ESnet and other national and international research backbones, plus commodity transit.
Notable
The evidence that settles the kind is the mismatch between address count and neighbour count. RIS sees a single announced IPv4 prefix, 152.55.152.0/22 (1,024 addresses), and one IPv6 prefix, 2607:f7b8::/32 — but 49 observed neighbours.
A network with 1,024 addresses and 49 BGP neighbours is not an enterprise and not an eyeball provider; those peer with a handful. Fifty adjacencies against a /22 means the addresses exist only to number the routers, and the point of the AS is the peering fabric itself. This is the classic signature of a regional R&E exchange: every connector institution shows up as a separate neighbour, while SoX itself holds almost no address space of its own.
Interesting
2607:f7b8::/32 is a direct ARIN allocation rather than a slice of Internet2's block — SoX carries a full /32 in its own right, which is more IPv6 than most of the campuses it connects, and reflects its role handing sub-allocations down to members.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
