While developing a tool to check all websites that we link to in the php.net
manual we found that the ftp.openldap.org doesn't point to a working ftp server
while using ipv6

AAAA record for ftp.openldap.org
$ php -r "var_dump(gethostbyname(gethostbyaddr('2001:4f8:3:ba:2e0:18ff:fe02:efec')));"
string(14) "204.152.186.50"
this servers gives a Connection Refused

A record for ftp.openldap.org
$ php -r "var_dump(gethostbyname('ftp.openldap.org'));"
string(14) "204.152.186.57"
This server works fine

Can you please fix/look into this error, ipv6 is getting used more and more
