Uppercase A record results in only last record being used

[aeden]

FQDN with uppercase letters in the A record's leftmost label resulted in only the last record being used.

When the zone cache receives the zone, does it make sense to downcase all the letters?

FQDN with uppercase letters in the A record's leftmost label resulted in only the last record being used.

I'm not showing this is the case anymore @aeden. Just tested adding a variation of ladp.example.com upper/down case letters at

erldns/priv/zones-example.json

Lines 97 to 104 in ddd790b

	{
	"name": "ldap.example.com",
	"type": "A",
	"ttl": 3600,
	"data": {
	"ip": "50.40.50.40"
	}
	}

and I was not able to reproduce it. Can you confirm? (even it was 10y ago 😅)
