So a quick look into this I see one potential real world example:
;; ANSWER SECTION:
google.com. 129 IN A 216.58.218.142
google.com. 74411 IN NS ns4.google.com.
google.com. 74411 IN NS ns1.google.com.
google.com. 74411 IN NS ns2.google.com.
google.com. 74411 IN NS ns3.google.com.
google.com. 3054 IN TXT "v=spf1 include:_spf.google.com ~all"
google.com. 64 IN AAAA 2607:f8b0:4000:802::200e
google.com. 54475 IN TYPE257 \# 19 0005697373756573796D616E7465632E636F6D
In RFC 6844 section 7.1 it states
"IANA has assigned Resource Record Type 257 for the CAA Resource Record Type"
and I am seeing:
google.com. 54475 IN TYPE257 \# 19 0005697373756573796D616E7465632E636F6D

So I’ve come across this on Qualys and just wondering if there’s any practical examples out there in the wild.
I know some BIND guys are on here, so I’m sure I’m missing something from the RFCs.
Just wanted to test this out on my play domains before putting it out in the wild...
