Any system or anyone who wants to access your domain has to resolve your A records. These records point to IPv4 addresses. You can make an online DNS A record lookup, and check IPv4 address of your domain.
DNS (Domain Name System) is a service that translates domain names into IP addresses. Users can easily remember domain names, but he computers understand IP addresses that’s why we need DNS. For example, without this service, you have to type '126.96.36.199' in your browser instead of www.facebook.com to access Facebook. IP - Domain mappings are kept on DNS servers. You can query those matches on securityforeveryone.com
There is two type of IP addresses IPv4, and IPv6. IPv4 address looks like these:
188.8.131.52 127.0.0.1 255.255.255.255
IPv6 addressed looks like these (all of them are the same IP):
::ffff:808:808 0:0:0:0:0:ffff:0808:0808 0000:0000:0000:0000:0000:ffff:0808:0808
DNS A record maps a domain to an IP address. “A record” stands for “address record” and to use a domain name, it must have an A record.
In order for people to access your domain name, your domain name needs to have a correct A record.
DNS A record must have a valid IPv4 address. Usually, domains have only one IPv4 address in their A records. But it can be more than one to provide redundancy.
Pretty Simple. Use our free and online DNS A Record lookup tool. Write your domain on the form on top of the page.
If you are using a Linux or an OS X operating system, open terminal and type dig -t a yourdomain.com. If your domain has a valid A record, it would look like that:
dig -t a securityforeveryone.com ;; ANSWER SECTION: securityforeveryone.com. 300 IN A 127.0.0.1
If you are using Windows open powershell and type Resolve-DnsName -Name yourdomain.com -Type A
If DNS A Record doesn't look the way you want, there are a few things you can do.
