Summary

Mansfield Independent School District

United States of America · AI-generated

education business static leased

MANSFIELDISD is the AS handle for Mansfield Independent School District.

What it's used for

  • The space carries static IP addresses, as indicated by reverse DNS entries like static-188-194-69-64.conterra.com and the netname DWLNET16.
  • The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, a ratio typical of a small, dedicated site or leased block rather than a large access network.

Notable

  • The RDAP registrant for the announced prefix is Conterra, which differs from the AS holder Mansfield Independent School District, suggesting the address space is leased or managed by a third party.
  • The inventory consists of a single /24 block (69.194.188.0/24) with no IPv6 prefixes, indicating a limited, IPv4-only footprint.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
