Check DNS Propagation Status
Verify whether recent DNS changes have propagated and the new records are live.
Look Up DNS Records
Query DNS records for any domain to inspect A, AAAA, MX, CNAME, TXT, and NS configurations.
Quick answer: Use the DNS Domain tool through ToolRouter to look up dns records directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolDNS records are the foundation of how the internet routes traffic, delivers email, and verifies domain ownership. When something breaks -- a website goes down, emails bounce, or a verification fails -- the first step is checking DNS records to see what is actually configured.
The lookup_dns skill queries DNS records for any domain and returns the full set of configured records. See A records pointing to your servers, MX records routing your email, TXT records for verification and SPF, and everything else. No need to remember dig syntax or switch between lookup tools.

Claude turns DNS investigation into a deep, conversational security review where each finding leads naturally to the next check. Ask Claude to look up your records, chain that into an SSL verification, cross-reference with email authentication settings, and explain the security implications of every configuration detail it finds. Its analytical reasoning makes it ideal for thorough domain audits where understanding the "why" behind each record matters as much as seeing the data.
How to look up dns records
Once connected (see setup above), use the DNS Domain tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- Ask Claude: "Look up all DNS records for example.com using dns-domain"
- Claude runs lookup_dns and returns the complete DNS record set
- Ask follow-up questions about specific records or potential issues
Example prompt
Try this with the DNS Domain tool
Look up all DNS records for our domain example.com. Show me A, MX, TXT, CNAME, and NS records.
Tips
- Ask Claude to explain what each record does if you are unfamiliar with DNS
- Check MX records when troubleshooting email delivery issues
- Look at TXT records to verify SPF, DKIM, and domain ownership entries
