ahost

ahost [-d] [-s server] [-t type] [-D domain] hostname

ahost is a DNS lookup utility that displays the A (IPv4) or AAAA (IPv6) records associated with a hostname or IP address. It uses the c-ares asynchronous DNS library to perform lookups, making it non-blocking and efficient.Unlike the more common host or dig commands, ahost is specifically designed as a lightweight demonstration and utility tool from the c-ares library. It supports reverse lookups (when given an IP address) and can query for specific record types.

-d

Display extra debugging output

Set the server list to use for DNS lookups

Display the record with a specified type: a for the A record, aaaa for the AAAA record, or u to look for both AAAA and A records (the default)

Specify the search domain instead of using the default values from /etc/resolv.conf (only on platforms that use /etc/resolv.conf)

Part of the c-ares library tools. May have different features compared to the more common host command.
