Perform a reverse DNS (PTR) lookup for an IPv6 address. A PTR record (Pointer Record) maps an IPv6 address to a hostname using the ip6.arpa domain. This lookup reveals the domain name associated with an IPv6 address and is commonly used for verification, logging, mail server checks, and network diagnostics.

Use !ptr-ip6 to retrieve the reverse DNS hostname for an IPv6 address. This command focuses on DNS PTR resolution. For IPv6 address analysis use !ip6; for IPv6 CIDR block analysis use !cidr6; for IPv6 WHOIS registration data use !whois-ip6; for BGP routing visibility use !bgp-cidr6.

Usage:
!ptr-ip6 <ipv6-address>

Usually, !ptr can be used in place of !ptr-ip6

Usage Examples:
!ptr 2a00:1450:4017:800::200e
!ptr 2001:502:4612::10
!ptr 2610:A1:32D1::53
