[Dnsmasq-discuss] Fwd: Errors in address FQDN name combinations with hyphens

[Dan Schaper]

The domain names in the second screenshot are IDNs, conversion of
unicode to ascii. See
https://en.wikipedia.org/wiki/Internationalized_domain_name#Example_of_IDNA_encoding
for more on that.
The ones in the first screenshot that generate errors also appear to be
valid.

Running 0p-1pvdwjev-qele.exactag.com through
https://dns.google/query?name=0p-1pvdwjev-qele.exactag.com and
http://sqa.fyicenter.com/1000207_Domain_Name_Validator.html both show
that domain as valid and Google resolves it to an  IP address. Checking
to see if the error is from line 2 that rolls over to line 3 shows valid
again https://dns.google/query?name=adrian---egn.000webhostapp.com.

The first listed domain name zzz.eric-prautsch.com is very valid. Just
like the single hyphen in my domain name.

Let me know if there is a question on that list, DeveloperDan is a good
friend of ours at Pi-hole.

Best,
Dan
