Or better, how about stop remembering every steps like:
> dig livedoor.blogimg.jp A
;; ANSWER SECTION:
livedoor.blogimg.jp. 1983 IN CNAME
ldblog-image-cdn.line-apps.com.
ldblog-image-cdn.line-apps.com. 1983 IN CNAME
blgimg.line-apps.com.akadns.net.
blgimg.line-apps.com.akadns.net. 1983 IN CNAME livedoor.edgesuite.net.
livedoor.edgesuite.net. 1983 IN CNAME a1887.w73.akamai.net.
a1887.w73.akamai.net. 1983 IN A 2.17.251.20
a1887.w73.akamai.net. 1983 IN A 23.216.134.101
--> DNSMASQ remembers every single CNAME steps and last A.
Do this instead, just like other public DNS would??

--> DNSMASQ will resolve the CNAME chain, but remember only the last
destination answer.
