Summary

Northern Crossroads (NoX) / New England GigaPoP

United States · AI-generated

education university research transit legacy

GIGAPOP-NE is registered to Harvard University but is not Harvard's campus network. It is the New England GigaPoP, operated as Northern Crossroads (NoX) — the regional research-and-education aggregation point for New England universities, with MIT and Harvard as anchor institutions and a membership running to a couple dozen colleges and research organisations.

What it's used for

The rDNS is the giveaway: the sampled address resolves to harvard-cps-nox300gw1.nox.org, a NoX gateway router, not a Harvard host. RIS sees 4 IPv4 prefixes carrying 24,832 addresses and 6 IPv6 prefixes, against 19 observed BGP neighbours.

That ratio is the whole story. Nineteen peers against a modest address count is not an eyeball network and not an enterprise — it is an aggregator. NoX exists to hand its member campuses shared upstream connectivity: Internet2 and national R&E backbones, commodity transit, and direct peering with large content networks, bought once at regional scale rather than a dozen times over. Traffic is university research and campus egress; the address space itself is mostly infrastructure.

Notable

Both IPv4 prefixes — 18.2.128.0/19 and 18.2.192.0/19 — sit inside 18.0.0.0/8, MIT's legacy Class A. The GigaPoP was numbered out of a member institution's historic block, which is why a multi-university regional network appears to live in MIT address space.

Interesting

One announced prefix, 2001:504:2e::/48, falls in ARIN's 2001:504::/32 range, which is reserved for exchange-point peering fabrics — the address-level fingerprint of an organisation that runs an interconnect, not just consumes one.

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.

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.
