This morning, Microsoft served a federal court order and seized 22 of our most commonly used domains because they claimed that some of the subdomains have been abused by creators of malware. No-IP has a very strict abuse policy and is constantly working to keep the No.IP system domains free of spam and malicious activity.

Microsoft now claims that it just wants to get us to clean up our act.”]
