Summary

Mindsong Enterprises

unknown · AI-generated

business small static

AS21695 is held by Mindsong Enterprises.

What it's used for

  • The address space carries business infrastructure, evidenced by the netname MAUIBUILT and reverse DNS entries like cray64.mauibuilt.com and cray127.mauibuilt.com.
  • The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, isolated business network rather than a transit or access provider.

Notable

  • The registrants for the two announced prefixes are distinct: Mindsong Enterprises for 204.145.255.0/24 and Maui Built Machines for 205.166.10.0/24.
  • The inventory consists of two /24 blocks, one of which is associated with a different registrant than the AS holder, suggesting a multi-entity or leased arrangement.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
