Domain & WHOIS Monitoring
Never lose a domain to an unexpected expiration.
Domain expiration is one of the most avoidable causes of website and email outages — yet it continues to happen because renewal notifications get lost in inboxes or go to former employees. NetTests monitors your domain registration details, expiry dates, and nameserver assignments, alerting you well in advance so renewals happen before anyone notices.
Domain expiration is more disruptive than it looks
When a domain expires, the impact is immediate and total. DNS stops resolving. The website goes offline. Email stops delivering. And depending on the grace period, recovering the domain may require paying a premium redemption fee — or in the worst case, the domain is acquired by a third party. Domain monitoring provides a reliable, independent safety net that doesn't depend on registrar notifications reaching the right inbox.
Nameserver changes are equally dangerous. An unauthorized change to a domain's nameservers redirects all DNS to a different provider, potentially pointing your website and email to attacker-controlled infrastructure. WHOIS monitoring that tracks nameserver assignments provides early detection of this class of domain hijacking attack.
