I find that to use the expungeByName cache command in dnsdist I have to end
the name with \013,  why is this?

An example that works would be:


If I leave out the ending \013 in the DNS name, like so:


 the entry is not deleted from the cache.

The entry in the dnsdist cache was loaded by running the following dig

dig @ -p 5200 +nocookie google.com
