    This document describes the error codes for CAT network quality tasks. The following error codes, if any, will be counted into top five error types in testing statistics.
    Error Code
    Definition
    Description
    601
    No server was found during the ping test.
    In a ping test, DNS query is performed to resolve the domain to be pinged to an IP, and then the ICMP packet is sent. This error code will be reported if an error occurs during domain resolution.
    602
    The number of tracert hops exceeds the limit.
    By default, there can be up to 30 hops in a tracert test. If the number of hops is set to a value smaller than 30, the configuration applies. This error code will be reported if the number of IPs in a tracert exceeds the limit.
    603
    The network environment test timed out.
    This error code applies to DNS query, ping, and tracert tests.
    605
    The tracert server is unreachable.
    The server will be regarded as unreachable if the tracert operation times out and already has five hops.
    606
    CNAME query failed.
    CNAME query failed in the DNS process.
    608
    The local DNS server could not be found.
    This error code will be reported if the local DNS server address cannot be obtained.
    609
    The DNS requests of all NS servers failed.
    Multiple NS servers are available for DNS query. The client will get the list of all NS servers and perform query operations one by one. DNS query is regarded as successful if one of the requests returns the DNS record successfully. This error code will be reported if the DNS requests of all NS servers fail.
    610
    The NS root servers could not be resolved.
    The iteration process requires the 13 NS root servers in the international domain system and cannot start if these servers cannot be resolved.
    611
    The intermediate NS server could not be resolved.
    The iteration process requires resolving the NS server under each domain in a top-down manner and will fail if the NS server under any domain fails to be resolved.
    612
    The domain does not exist.
    The NS server returned an error code to notify the local server that the domain does not exist.
    613

    The NS server returned another error code.
