-You can use tools like [nslookup](/windows-server/administration/windows-commands/nslookup) to verify availability and content of DNS records from the client end, and use tools like [ping](/windows-server/administration/windows-commands/ping) or [tracert](/windows-server/administration/windows-commands/tracert) to check reachability of IP addresses.
