ohio-state.edu TXT Record Lookup
Use this TXT record lookup tool to view all text-based DNS records for ohio-state.edu. TXT records are commonly used for email authentication (SPF, DKIM, DMARC), domain ownership verification, and other purposes.
//01
What Are ohio-state.edu's TXT Records?
TXT (Text) records for ohio-state.edu contain text strings published in DNS. While originally designed for human-readable notes, TXT records are now primarily used for machine-readable data like email authentication policies and domain verification tokens.
ohio-state.edu's TXT records reveal important information about the domain's email security configuration, which services have verified ownership of ohio-state.edu, and any other text-based DNS data the domain administrators have published.
Each TXT record can hold up to 255 characters per string, though a single record can contain multiple strings concatenated together. Large records like DKIM keys often use this multi-string format.

Common TXT Record Types
SPF (Sender Policy Framework) records start with "v=spf1" and specify which servers are authorized to send email on behalf of ohio-state.edu. These are critical for preventing email spoofing and improving deliverability.
DKIM (DomainKeys Identified Mail) public keys are stored as TXT records under selector subdomains (e.g., selector._domainkey.ohio-state.edu). DMARC policies are published at _dmarc.ohio-state.edu and control how receiving servers handle unauthenticated email.
Domain verification records are used by services like Google ("google-site-verification=..."), Microsoft ("MS=..."), Facebook ("facebook-domain-verification=..."), and Apple ("apple-domain-verification=...") to confirm that ohio-state.edu's owner has authorized the service.

Understanding ohio-state.edu's TXT Records
TXT records may appear cryptic at first, but most follow standard formats. Look for known prefixes to identify the type: "v=spf1" for SPF, "v=DMARC1" for DMARC, "v=DKIM1" for DKIM keys, and service-specific verification strings.
If ohio-state.edu has an SPF record, it defines which IP addresses and services are allowed to send email as ohio-state.edu. The presence of DMARC and DKIM records indicates stronger email authentication. Verification records confirm that ohio-state.edu is linked to specific third-party services.
