DNS lookup — common questions

How do I find the IP address of a domain?

Enter the domain above and look at the A record (IPv4) and AAAA record (IPv6) — those are the IP addresses the domain resolves to. A domain can have several IPs for load-balancing or CDN delivery, so you may see more than one.

What are the different DNS record types?

A and AAAA map a name to an IPv4/IPv6 address; CNAME aliases one name to another; MX lists the mail servers (with priorities); NS lists the authoritative nameservers; TXT holds text records (SPF, DKIM, domain verification). This tool returns all of them at once.

Why does a domain return more than one IP?

Large sites publish multiple A/AAAA records so traffic spreads across servers (round-robin DNS) or so a CDN can return the nearest edge. Any of the listed IPs is valid; clients pick one.

Is this lookup live and accurate?

Yes — the query is resolved in real time by our server using the standard DNS resolver, not a cached third-party API, so you see current records. DNS changes can take time to propagate globally, so a very recent change may not appear everywhere yet.

What can I do with the IP I find?

Drop it into our subnet calculator to see its network and scope, check whether it is public or in a known range, or plan firewall/ACL rules. For network design, segmentation and managed DNS, Servnet can help.
