Features include on-the-fly zone addition and removal, zone transfer between servers, DDNS (dynamic updates), NSID (RFC 5001), EDNS0 extensions, and DNSSEC (including NSEC3), along with response rate limiting (RRL). <\/p>\n<p>In the new release:<\/p>\n<ul>\n<li class=\"l\"> A high-performance networking mode has been implemented using the eXpress Data Path subsystem, which provides means for packet processing at the network driver level before being handled by the Linux kernel network stack. This mode requires Linux kernel 4.18 or newer. <noindex><a rel=\"nofollow\" href=\"https:\/\/www.iovisor.org\/technology\/xdp\">XDP<\/a><\/noindex> Support for Catalog Zones has been added, simplifying the maintenance of secondary DNS servers.
