I did it manually previous, without results collected, i tried to
tcptraceroute too (expecting that they responds to TCP requests),
etc. I used ping output to demonstrate the problem.
I do not know what dig's return code 9 means:
ns0.sorbs.net. 113.52.8.11 dig fail 9
ns2.sorbs.net. 87.106.246.125 dig fail 9

rbldns12.sorbs.net. 74.208.146.124 dig fail 9
rbldns13.sorbs.net. 113.52.8.157 dig fail 9
rbldns6.sorbs.net. 194.134.35.204 dig fail 9

While i didn't compare it side by side with ping, it +- corresponds with
ping results, at least in mean, that some responds and some not.
Here is one example of result with code 9:
; <<>> DiG 9.11.5-P4-5.1+deb10u6-Debian <<>> @113.52.8.11
163.44.213.129.safe.dnsbl.sorbs.net ; (1 server found) ;; global
options: +cmd ;; connection timed out; no servers could be reached
