DNS downtime: Meaning
A DNS outage, also known as DNS downtime, is when the DNS is not functioning correctly. This implies that the IP address won’t be visible if you look for the domain name. Users will instead utilize DNS requests to find your domain. The domain’s authoritative nameserver will be requested by the DNS recursive server, but it will not respond and instead receive an error message.

Nslookup command explained
The Nslookup command is a helpful and very useful tool with a command-line interface (CLI). The abbreviation “nslookup” is short for “name server look up”. Typically, it is utilized for finding the IP address of a particular host or performing a Reverse DNS Lookup which is a process of finding a domain name that is associated with an IP address (IPv4 or IPv6). In most cases, it is pre-built on almost every operating system (OS). That is why it is a very popular choice for administrators.

From what we know, there are a lot of DNS record types. They are a critical component of the Domain Name System process. In this article, we will define them and discuss which types of records are most important.
DNS record – what is it?
DNS records are text instructions kept in zone files that allow domain names to be resolved to IP addresses (A record and AAAA record). They are very light and simple to edit (if necessary) and depend on the type of query. In view of the fact that computers are not human, they use records to understand and read texts. That is, they convert the written file into numbers that machines can interpret.
