Hello,
in `https://www.freepascal.org/docs-html/current/rtl/sockets/netaddrtostr6.html`, it is written:
<quote>
NetAddrToStr6 converts the IPV6 network address in Entry to a string representation in human-readable form.
Basically, it is the same as NetAddrToStr6, but with the bytes in correct order. </quote>
I think that the second "NetAddrToStr6" should be something else, probably "HostAddrToStr6".
