Note the differences in how the addresses must be formatted: .P1 ; ndb/csquery > tcp!ircnow.org!443 /net/tcp/clone 198.251.82.194!443 ; ndb/dnsquery > ircnow.org ipv6 ircnow.org ipv6 2605:6404:2d3:: .P2 .PP Note: All addresses in plan 9 are IPv6 addresses. So an ipmask=/123 for an IPv4 address is actually an IPv4 /27 subnet. Note: when you lookup a name using whatever nameserver is defined in /lib/ndb/local, if it's not found, ndb will recursively search the root nameservers to find the entry Most resolvers will normally give up, but ndb is really persistent. To run a caching DNS server, modify /cfg/$sysname/termrc or /cfg/$sysname/cpurc (whichever is appropriate) to include the following: ndb/dns -rs Be aware that there are no access controls to this caching server. This makes the server vulnerable to being used in a DDoS amplification attack using DNS. You will need to firewall off access.
