IP Address: 165.127.240.13

The address is registered to The Governor's Office of Information Technology (COGGCC-NET). Enterprise-registered addresses that appear in DMARC failure data are typically either compromised hosts on the organization's network or outbound mail relays that are not properly authorized in the domain's SPF record.

Across the wider COGGCC-NET network, 2 distinct IPs have been associated with 18 authentication failures over 99 observed messages, spanning 1 country. Activity on this network is sparse in this dataset, suggesting isolated rather than systematic abuse.

If your domain appears in the From header of mail from this address, treat it as probable spoofing. Verify that your SPF record does not authorize this host, directly or through nested include mechanisms, and that no DKIM selector you publish has been issued to it. If both checks come back clean, the receiver's none enforcement action is doing its job.

Your DMARC policy posture matters more than any IP-level response here. A p=none policy provides visibility but no enforcement, meaning mail is reported but not blocked. Moving to p=quarantine and then p=reject closes the gap for attackers who manage partial alignment. Domains that remain at p=none long-term tend to be impersonated repeatedly, because the cost to the attacker of attempting is effectively zero.

Blocking this individual address has limited durability: an attacker can rotate to another address in the same /24 subnet at effectively zero cost. More durable responses include monitoring aggregate DMARC reports so new sources are visible as they emerge, tightening SPF to remove overly permissive include chains or +all mechanisms, and ensuring DKIM is signing every legitimate outbound stream so alignment failures are unambiguous. The formal abuse contact for The Governor's Office of Information Technology is listed in ARIN WHOIS records, and timely remediation is achievable through that channel.
