.TH dns_name6_domain 3 .SH NAME dns_name6_domain \- construct host name for reverse lookup .SH SYNTAX .B #include int \fBdns_name6_domain\fP(char \fIq\fR[DNS_NAME6_DOMAIN], const char* \fIip\fR[16],int \fItype\fR); .SH DESCRIPTION dns_name6_domain is a low-level component of dns_name6. It converts an IP address such as 4321:0:1:2:3:4:567:89ab into a domain name such as b.a.9.8.7.6.5.0.4.0.0.0.3.0.0.0.2.0.0.0.1.0.0.0.0.0.0.0.1.2.3.4.IP6.INT and places the packet-encoded domain name into \fIq\fR. \fItype\fR can be DNS_IP6_INT or DNS_IP6_ARPA. The "ip6.int" domain for IPv6 reverse lookups is now deprecated and "ip6.arpa" is the standard way. .SH "SEE ALSO" dns_name6(3), dns_name4_domain(3)
