REVIEW

No IPv6 support

No IPv6 (AAAA) records found

IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

No IPv6 Support

About 40% of internet users have IPv6. Consider adding AAAA records.

IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

Why this matters

No AAAA records — same impact as 'no IPv6 (AAAA) records'; IPv6-preferring clients pay extra latency falling back to IPv4.

Recommended actions

Add includeSubDomains to the HSTS directive
Add the preload directive and submit to hstspreload.org once max-age + includeSubDomains are in place
Enable DNSSEC on your domain for DNS spoofing protection
Enable OCSP stapling on your TLS server to remove a CA roundtrip and protect user privacy

DNS Records

1 A records, 1121 ms lookup

PASS

1 A records, 1121 ms lookup

Resolves to 1 IPv4 address(es)

Got: 23.185.0.3

Single A record — no DNS redundancy

Multiple A records provide failover if one server goes down.

No IPv6 (AAAA) records

8 nameserver(s) configured

Got: ns4.OAR.NET, ns.CWRU.edu, ns4.CWRU.edu, ns5.OAR.NET, ns2.CWRU.edu, ns7.OAR.NET, ns6.OAR.NET, ns3.CWRU.edu

1 mail exchanger(s) configured

CAA records not checked

CAA record lookup requires a specialized DNS resolver. This check will be available in a future update.

SPF record present in TXT

DNS resolution is slow (1121 ms)

Slow DNS adds latency to every page load. Consider a faster DNS provider.

CAA	Lookup not available with standard resolver

Resolved in 1121 ms

Multiple A records provide failover if one server goes down.

Why this matters

Single A record means a single point of failure — if that IP goes down, your site is unreachable until DNS TTL expires.

Learn more ▾

Add multiple A records for round-robin failover, or use a managed DNS provider with health-checked failover (Route 53, Cloudflare, NS1). Short TTL (60-300s) lets clients recover faster on outages.

CAA record lookup requires a specialized DNS resolver. This check will be available in a future update.

Why this matters

Informational: CAA (Certification Authority Authorization) records weren't checked in this scan.

Slow DNS adds latency to every page load. Consider a faster DNS provider.

Why this matters

DNS resolution is slow — anycast DNS providers (Cloudflare, Route 53) typically resolve <50ms globally.
