Well, its not doing anything by default. But can be turned on to gain.

Just be aware that your firewall and routing software all along the DNS
pathways needs to support EDNS0 and large UDP packets. Its off by
default because some popular devices (cheap Cisco kit / Linksys /
DynaLink in my experience, but not necessarily only them) often crash
when these type of DNS packets are delivered over them.
