DNS Lookup — Check DNS Records Online

The 101IP DNS Lookup tool lets you instantly query DNS records for any domain — A, AAAA, MX, NS, TXT, CNAME and SOA — without registration, directly in your browser.

What DNS record types does 101IP check?

• A — IPv4 address the domain resolves to;
• AAAA — IPv6 address;
• MX — mail exchange servers for the domain;
• NS — nameservers that manage the domain;
• TXT — text records (SPF, DKIM, domain verification, etc.);
• CNAME — canonical name (alias) pointing to another domain;
• SOA — start of authority: primary nameserver, admin email, serial number.

When is DNS Lookup useful?

• verifying correct domain delegation after moving to a new hosting;
• checking mail server (MX) records when configuring email;
• diagnosing DNS propagation and checking if records have updated;
• verifying SPF, DKIM and DMARC records for email deliverability;
• quick lookup of IP address or CNAME for any domain.
