Diagnose

DNS Tools

Resolve names, reverse lookup IPs, trace DNS paths, and flush resolver caches.

ripnet/src/dns.c

DNS Lookup

Resolves a hostname with the system resolver.

-d HOST
ripnet --dns-lookup HOST
ripnet --dns-lookup example.com
ripnet -d example.com

Reverse Lookup

Finds the PTR hostname for an IP address.

-r IP
ripnet --dns-reverse IP
ripnet --dns-reverse 8.8.8.8
ripnet -r 8.8.8.8

Record Query

Runs a DNS query path for the host.

-q HOST
ripnet --dns-query HOST
ripnet --dns-query example.com
ripnet -q example.com -Z 1.1.1.1
Options
  • --dns-server SERVER
Notes
  • The parser currently accepts the host as the query argument; the record-type field exists internally but is not populated by a second positional argument.

DNS Server Test

Sets a DNS server value for query-oriented DNS checks.

ripnet --dns-server SERVER --dns-query HOST
ripnet --dns-query example.com --dns-server 8.8.8.8
Notes
  • The command is selected by --dns-query; --dns-server is an option, not a standalone command.

DNS Trace

Traces DNS resolution for a hostname.

-Y HOST
ripnet --dns-trace HOST
ripnet --dns-trace example.com
ripnet -Y example.com

Flush DNS Cache

Requests a platform DNS cache flush.

-Q
ripnet --dns-cache-flush
ripnet --dns-cache-flush
ripnet -Q
