# DNS Change Monitoring ### What is the purpose of DNS change monitoring? Your DNS records act like a signpost. When a visitor types in your website's address, the DNS records tell the user's browser which hosting server to visit to find the website. It also tells email providers where to find your email accounts, it also helps to verify your domain and improve the deliverability of your sent emails. Your DNS records are the technical backbone to the whole digital aspect of your business. You will occasionally need to make changes to your DNS records, maybe when changing hosts or when a new service needs you to authenticate your domain. Either by accident or by maliciousness, DNS changes can happen that affect or bring down your website and/or email accounts. You need to know both when changes happen that you were not expecting and what the records were before the change. This information together helps you quickly rectify the situation. ### How does it function? Our DNS change monitoring will check periodically for any alterations to your records. The package you choose determines how often the records are checked. At the top level, they are checked every 24 hours. If any changes are noted, we will let you know that a record has been altered and the changes seen. We can also assess any impact of the change, depending on the type of change noticed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
