!scan-headers-ip6 performs a live probe of Internet services running on an IPv6 host and retrieves their headers and banners. This allows you to inspect how a service identifies itself, what metadata it returns, and whether it exposes diagnostic information useful for troubleshooting in the IPv6 Internet.

Service headers often reveal details such as software versions, supported protocol features, redirection behavior, or security capabilities. By examining these responses, you gain insight into how a remote IPv6 host is configured and how it communicates with clients across the Internet.

This command performs a real‑time probe and, in keeping with good Internet citizenship, may transmit your public IP address to the target service.

You may also use !scan-headers in place of !scan-headers-ip6

!scan-headers-ip6 commands have the following structure:
!scan-headers-ip6
  [<IPv6_Address>]:<Port_Number>
  (<Transport_Protocol>) [TCP|UDP --default: TCP]
  (<App_Protocol>) [None|HTTP|SMTP|IMAP --default: None]


Usage:
!scan-headers-ip6 [<ipv6-address>]:<port-number> (tcp|udp) (none|http|smtp|imap)
