Summary

AT&T

unknown · AI-generated

mobile business enterprise

AS64011 is operated by AT&T.

What it's used for

  • The address space carries mobile subscriber traffic, evidenced by reverse DNS names such as mobile.mymmode.com and mobile.mycingular.net, alongside enterprise infrastructure indicated by the netname AEL-360.
  • The AS announces 82,944 IPv4 addresses and 33 IPv6 prefixes with only 2 observed neighbours, a ratio characteristic of an access network rather than a transit provider.
  • Traffic from this AS consists of mobile device data and enterprise connectivity, consistent with AT&T's role as a major telecommunications carrier.

Notable

  • Registrants include both AT&T Enterprises, LLC (for AEL-360 and ATT-MOBILITY-LLC blocks) and Worcester Polytechnic Institute (for WPI), indicating a mix of corporate and academic address space within the same AS.
  • The inventory includes a /16 block registered to Worcester Polytechnic Institute, which contrasts with the predominantly mobile and enterprise nature of the remaining prefixes.

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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
