That is not correct. For quite some time that address is a hardwired to avoid problems DNS problems (https://dev.gnupg.org/T3755): /* We used to have DNS CNAME redirection from the URLs below to * sks-keyserver pools. The idea was to allow for a quick way to * switch to a different set of pools. The problem with that * approach is that TLS needs to verify the hostname and - because * DNS is not secured - it can only check the user supplied hostname * and not a hostname from a CNAME RR. Thus the final server all * need to have certificates with the actual pool name as well as * for keys.gnupg.net - that would render the advantage of * keys.gnupg.net useless and so we better give up on this. Because * the keys.gnupg.net URL are still in widespread use we do a static * mapping here. */ if (!strcmp (uri, "hkps://keys.gnupg.net") || !strcmp (uri, "keys.gnupg.net")) uri = "hkps://hkps.pool.sks-keyservers.net"; else if (!strcmp (uri, "https://keys.gnupg.net";)) uri = "https://hkps.pool.sks-keyservers.net";; else if (!strcmp (uri, "hkp://keys.gnupg.net")) uri = "hkp://hkps.pool.sks-keyservers.net"; else if (!strcmp (uri, "http://keys.gnupg.net";)) uri = "http://hkps.pool.sks-keyservers.net";; else if (!strcmp (uri, "hkps://http-keys.gnupg.net") || !strcmp (uri, "http-keys.gnupg.net")) uri = "hkps://ha.pool.sks-keyservers.net"; else if (!strcmp (uri, "https://http-keys.gnupg.net";)) uri = "https://ha.pool.sks-keyservers.net";; else if (!strcmp (uri, "hkp://http-keys.gnupg.net")) uri = "hkp://ha.pool.sks-keyservers.net"; else if (!strcmp (uri, "http://http-keys.gnupg.net";)) uri = "http://ha.pool.sks-keyservers.net";; Shalom-Salam, Werner -- Die Gedanken sind frei.
