Welcome to online domain a record lookup
tool. This version of a record checker
working for domain names only,
here you will find full A records list for domain, and some geo ip information like country,region,city,ISP.
Domain A lookup
can be used for find all IP's od domain (see additional info section).
So A record returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but also used for DNSBLs, storing subnet masks in RFC 1101, etc.
It's very important functionality, and domain will not work propertly (or fully) with out A record. So if you have a problem like "Browser can't find the server at 2sdfsdewqeef.com.", you must understand that browser searching server with "domain name", but TCP/IP connection opening with using IP address.
thats why you can try to find a record
first of all, and only after it's a record check success - you can try to check server for accessibility via port 80.
DNS records - it's one of most important part of domain settings,it naming system for computers, services, or any resource participating in the Internet.
you can click to any domain in search result and get full dns records list.
