Summary

Interphase Communications

United States of America · AI-generated

hosting business us

IPHASE-AS is operated by Interphase Communications, Inc.

What it's used for

  • The address space carries hosting and business services, evidenced by netnames such as NWBW-IP-BLK001 and EXO-XO1, and reverse DNS entries like krantzsecure.com and ev6.srm.prsvrs.com.
  • The AS announces 1536 IPv4 addresses across 6 prefixes with 5 observed neighbours, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web and API endpoints for hosted services, consistent with the operator's role as a network services provider.

Notable

  • Registrants largely align with the announcer, with Interphase Communications, Inc. listed for most prefixes, though 192.225.167.0/24 is registered to RW-194 and 192.225.174.0/24 to Alpha1Servers, LLC.
  • The address inventory is composed of six /24 blocks within the 192.225.160.0/22 range, showing a compact and contiguous allocation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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.
