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 '220.127.116.11' 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:
18.104.22.168 127.0.0.1 255.255.255.255
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
An TXT record is used to hold any text value associated with your domain name. This type of records usually used for, proof for ownership of domain (google, yandex verification), Sender Policy Framework (SPF) records or DKIM.
Type your domain name on the form above to make a free, online and easy DNS TXT record lookup. If you want to learn other ways, continue to read.
Or if you are using a Linux or an OS X operating system, open terminal and type dig -t txt yourdomain.com. If your DNS server respond to DNS TXT query it would look like this:
dig -t TXT securityforeveryone.com ;; ANSWER SECTION: securityforeveryone.com. 299 IN TXT "yandex-verification: 4f2ac2ecaf778a7d" securityforeveryone.com. 299 IN TXT "v=spf1 redirect=_spf.yandex.net"
If you are using Windows open powershell and type Resolve-DnsName -Name yourdomain.com -Type TXT
If you cannot see TXT records that you want, you need to go where you manage the DNS records (usually the hosting provider panel) and check TXT records.
