Summary

DownCity LLC

United States · AI-generated

isp hosting legacy

DOWNCITY is DownCity LLC, a small Connecticut internet company registered at an address in Norwich, CT. Public records describe it as a late-1990s regional provider offering dial-up access, web design, web hosting and business services.

What it's used for

Whatever it carries today, it carries very little of it. RIS shows a single announced IPv4 prefix, 199.105.120.0/21, totalling 2,048 addresses, no IPv6, and 1 observed BGP neighbour. One prefix behind one upstream is the minimum viable footprint for an autonomous system: it buys transit from a single provider and originates nothing else.

That shape is consistent with a legacy regional ISP that has shrunk, been absorbed, or now exists mainly to keep an address block routed. The evidence available here does not establish what the /21 currently serves, and no reverse DNS was returned on the small sample taken, which proves nothing either way. Rather than guess between dial-up remnant, hosting, or a reassigned block, this card stops at what is observable: a legacy /21 with a single upstream.

Notable

The handle invites a wrong guess. "Downcity" is the local nickname for downtown Providence, Rhode Island, and there was a well-known Providence restaurant by that name. The AS holder is neither. It is a Connecticut company, and the resemblance is coincidence, a reminder that an ASN handle is a string somebody typed, not a fact about geography.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
