Summary
InterWorld Communications, Inc.
hosting isp legacy
The network of InterWorld Communications, Inc., an independent provider based in Torrance, California, serving the Los Angeles South Bay since the mid-1990s. Handle INTERWORLD.
What it's used for
- Business connectivity and colocation: the company sells circuits, wireless links, server colocation and web hosting to customers in its area.
- Originates around 19 prefixes, mostly
206.124.xand207.136.x/24s, with hosted customer sites spread across them.
Notable
- A regional, business-focused provider rather than a mass-market broadband ISP: the address space is split between customer circuits and hosted servers.
- A genuine 1995-era ARIN registration, and one of the small independents that has kept originating its own routes long after most of its contemporaries were absorbed.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,784 prefixes, as published 2026-10-19. 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.
