GTM nameserver records not reponding

Creating zones in zonerunner shouldn't affect any GTM activity, because the order of processing will be that it attempts to handle the query with GTM long before it tries bind, and zonerunner is just manipulating the bind zone files.

The reason I suggested deleting the wideips and recreating them is that when you create a wideip (one that has a pool associated with it), GTM will populate the bind zone with those values (as a fallback mechanism). It will also do that if you change the gtm pool members associated with the wideip, so that's a workaround. If neither is possible, you'll can just edit the zone's A-records manually with zonerunner.

DNS Express is a marketing term, we changed the GUI in 11.5.0 and later to just say 'Zones', so what you see under Zones / Zone is actually DNS express (though do ensure it is turned on in your DNS profile - it is enabled by default, and a nameserver is set up): DNS Express (11.5.x) : https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/dns-services-implementations-11-5-0/1.html

The GUI menu anomaly is in 11.5.x, not just 11.5.1. It is fixed in 11.6.0 and 12.0.0 - it correctly shows zones:zonerunner in those versions

Did I miss anything ?
