Achim55, The paid lookups that ipcheck uses differ from the free lookups. From the website (may require login):
How Do Free Lookups Compare to Paid Plan Lookups?
You're likely missing fraud and high risk IP addresses! All of IPQS paid plans have access to better blacklists that significantly expand behavior patterns and detection rates for high risk IPs. Many of the worst IP addresses that facilitate abusive users online are via residential proxies. Our paid plans have access to premium blacklists with millions of active residential IP addresses & compromised devices collected by proprietary honeypots and botnet infiltration. Free account plans are limited to checking only a small portion of that data, leaving large gaps in coverage. SQLQuery me! 15:09, 9 January 2020 (UTC)
I see, thank you very much. So we can trust ipcheck's info ;) Cheers, --Achim (talk) 15:12, 9 January 2020 (UTC)
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
You can no longer read Wikimedia wikis if your browser use very old TLS. This is because it is a security problem for everyone. It can lead to downgrade attacks. Since 9 December you just see a warning. Soon the browser will not connect to the wikis at all. Most are users on Android systems older than 4.4. You can read the browser recommendations. 
Wikis can protect pages so that only some users can edit them. The standard protection levels are Require autoconfirmed or confirmed access and Require administrator access. If your wiki use more protection levels the technical name might be renamed for standardisation. This doesn't affect what users see. 
The new version of MediaWiki will be on test wikis and MediaWiki.org from 14 January. It will be on non-Wikipedia wikis and some Wikipedias from 15 January. It will be on all wikis from 16 January (calendar).
Deepcat and Catgraph will stop working. This will happen at the end of January. This is because you can now use the normal search function instead. 
You can use <ref follow="…"> to merge footnotes that follow each other. It is meant to be used for digitised books on Wikisource. If the order of the footnotes is wrong no error was shown but the bad <ref> was shown outside the <references /> list. This will change and you will see an error message instead.
