They account for a significant proportion of internet traffic and are therefore highly dependent on a stable, secure Swiss internet.</p> <h4>How is it measured?</h4> <p>Initially, we measured the number of distinct resolvers that query a.nic.ch and b.nic.ch for each domain. The queries do not only originate from web services, but also from email and all other internet services. From february 2019 on (i.e. data from february 2019) our method changes slightly<sup>1.</sup> We now measure the distinct number of ASes per domain instead of the distinct number of resolvers.</p>

In the event of technical problems, SWITCH informs the operator and makes recommendations for resolving them. As such, the DNS Health Report improves the reliability of the internet in Switzerland.</p> <p>SWITCH tests all .ch and .li <strong>domain names</strong> which are signed with DNSSEC. The test checks whether a DNSSEC-signed domain name can be resolved over a validating recursive resolver.</p> <p>In addition, all <strong>name servers</strong> which host .ch and .li domain names are tested. The name server addresses are tested for compliance with DNS standards using the following tests:</p> <ul> <li>TCP: checks if DNS messages over TCP succeed as DNS messages may be delivered using UDP or TCP communications. Also see <a href="https://tools.ietf.org/html/rfc7766">RFC 7766</a>.</li> <li>EDNS: checks EDNS compliance. The server must either comply with the original DNS standard from 1987 (<a href="https://tools.ietf.org/html/rfc1035">RFC 1035</a>) or the newer EDNS standards from 1999 (<a href="https://tools.ietf.org/html/rfc2671">RFC 2671</a> and <a href="https://tools.ietf.org/html/rfc6891">RFC 6891</a>). Note that supporting EDNS is not a requirement.</li> <li>EDNS Cookie: checks EDNS cookie compliance. As in the EDNS test, the server must respond with an EDNS-compliant answer (but supporting EDNS is not a requirement). If the server supports EDNS, the answer must also be EDNS cookie-compliant. Also see <a href="https://tools.ietf.org/html/rfc7873">RFC 7873</a>.</li> <li>Query Type: checks if the server returns a response to a more recent query type, such as CDS. The expected behaviour is a data or NODATA response. A NODATA response means there are records for the requested domain name, but none of them match the query type in the request. A data response would be an actual CDS record for example.</li> </ul> <h4>Data</h4></div></div></div> <div> <ul> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250217.jsonl.gz'>20250217.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250218.jsonl.gz'>20250218.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250219.jsonl.gz'>20250219.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250220.jsonl.gz'>20250220.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250221.jsonl.gz'>20250221.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250222.jsonl.gz'>20250222.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250223.jsonl.gz'>20250223.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250224.jsonl.gz'>20250224.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250225.jsonl.gz'>20250225.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250226.jsonl.gz'>20250226.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250227.jsonl.gz'>20250227.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250228.jsonl.gz'>20250228.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250301.jsonl.gz'>20250301.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250302.jsonl.gz'>20250302.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250303.jsonl.gz'>20250303.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250304.jsonl.gz'>20250304.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250305.jsonl.gz'>20250305.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250306.jsonl.gz'>20250306.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250307.jsonl.gz'>20250307.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250308.jsonl.gz'>20250308.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250309.jsonl.gz'>20250309.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250310.jsonl.gz'>20250310.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250311.jsonl.gz'>20250311.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250312.jsonl.gz'>20250312.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250313.jsonl.gz'>20250313.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250314.jsonl.gz'>20250314.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250315.jsonl.gz'>20250315.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250316.jsonl.gz'>20250316.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250317.jsonl.gz'>20250317.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250318.jsonl.gz'>20250318.jsonl.gz</a></li> <li><a href='/open-data/healthreport/nsscan-od-swish.switch.ch-20250319.jsonl.gz'>20250319.jsonl.gz</a></li> </ul> </div> </div> </div> <div id="tab-fccd70a3-b98e-11ed-9a74-5254009dc73c-3" class="tab-pane "> <div ><div> <div> <div ><p>The .ch & .li zone files, containing all delegated domain names, are publicly available for download. Access is restricted for the purposes of combating cybercrime, scientific and social research or for other purposes in the public interest, as e.g., foreseen by <a href="https://www.admin.ch/opc/de/classified-compilation/20141744/index.html#a10">Article 10(1)(a)(6)</a> of the <a href="https://www.admin.ch/opc/de/classified-compilation/20141744/index.html">Ordinance on Internet Domains</a>.</p> <h3>Access to the zone file data </h3> <p>The zone files are available by doing a DNS zone transfer (AXFR) from zonedata.switch.ch. using the following TSIG keys:</p> <pre># filename ch_zonedata.key<br />key tsig-zonedata-ch-public-21-01 { algorithm hmac-sha512; secret "stZwEGApYumtXkh73qMLPqfbIDozWKZLkqRvcjKSpRnsor6A6MxixRL6C2HeSVBQNfMW4wer+qjS0ZSfiWiJ3Q=="; };<br /><br /># filename li_zonedata.key<br />key tsig-zonedata-li-public-21-01 { <br /> algorithm hmac-sha512;<br /> secret "t8GgeCn+fhPaj+cRy1epox2Vj4hZ45ax6v3rQCkkfIQNg5fsxuU23QM5mzz+BxJ4kgF/jiQyBDBvL+XWPE6oCQ=="; <br />};</pre> <p>By downloading the .ch or .li zone file, you agree to use the zone file data only for combating cybercrime, scientific and social research or for other purposes in the public interest.
