The AS handle PHX-DATACENTER is held by Crexendo Business Solutions, Inc.

What it's used for

  • The address space carries cloud communications and unified communications traffic, evidenced by reverse DNS entries such as IP-184.178.213.64.crexendo.com, utwww2.solint.net, and mail1.storesonline.com.
  • The network announces 1280 IPv4 addresses across 4 prefixes with 2 observed neighbours, indicating a small-scale business network rather than a transit or large access provider.
  • Traffic from this AS consists of VoIP media and signalling, web/API endpoints, and collaboration services for Crexendo's cloud communications platform.

Notable

  • All registrants for the announced prefixes are Crexendo Business Solutions, Inc., matching the AS holder.
  • The address inventory is compact, consisting of four distinct IPv4 prefixes with no IPv6 announcements.
  • The netnames include NETBLK-CREX-1 and NETBLK-PHX-OFHFC-CREX-68-106-64-0, reflecting the company's Phoenix-based operations.

Reputation

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
