List of hosts which are allowed to be used in URL-related storage engines and table functions. When adding a host with the \<host\> xml tag:

it should be specified exactly as in the URL, as the name is checked before DNS resolution. For example: <host>clickhouse.com</host>
if the port is explicitly specified in the URL, then host:port is checked as a whole. For example: <host>clickhouse.com:80</host>
if the host is specified without a port, then any port of the host is allowed. For example: if <host>clickhouse.com</host> is specified then clickhouse.com:20 (FTP), clickhouse.com:80 (HTTP), clickhouse.com:443 (HTTPS) etc are allowed.
if the host is specified as an IP address, then it is checked as specified in the URL. For example: [2a02:6b8:a::a].
if there are redirects and support for redirects is enabled, then every redirect (the location field) is checked.

For example:

<remote_url_allow_hosts>
    <host>clickhouse.com</host>
</remote_url_allow_hosts>
