LookupLab
ChatGPT pluginCheck phone, email, IP and DNS
Check a phone number's carrier and line type, inspect an email's syntax and domain, look up approximate IP location and network, or inspect MX, SPF, DMARC and DKIM records. Connect your LookupLab account with OAuth. The plugin does not place calls, send messages or change DNS. Carrier data does not verify a person's identity or consent. Email checks do not prove mailbox ownership or guarantee delivery. IP location is approximate and some network fields may be unavailable.
