NsLookup.io DNS Monitoring watches domain records and alerts users when entries are added, changed, or removed.
What NsLookup.io is
NsLookup.io DNS Monitoring watches domain records and alerts users when entries are added, changed, or removed. The web service supports A, AAAA, MX, CNAME, NS, TXT, SOA, and CAA records, with configurable check intervals and change detection described as real-time. Baseline snapshots provide comparisons, while timestamped history records an audit trail. Notifications can go through email, Slack, or webhooks, and users can acknowledge expected changes to separate planned updates from changes needing attention. Its dashboard shows monitored domains, current records, recent changes, and alert status. The service is presented for organisations monitoring DNS for security and compliance. The Free plan is billed at $0/month and includes unlimited domains, configurable intervals, all features, and no credit card or setup fees. NsLookup says it processes but does not store IP addresses used to serve requested pages, while IP query counts may be retained for up to one hour to prevent abuse.
