Corrected Text
--------------
10   IN TYPE260  \# (
       18 ; length
       0a ; precedence=10
       02 ; D=0, relay type=2, an IPv6 address
       20010db8000000000000000000000015 ) ; 2001:db8::15
10   IN TYPE260  \# (
       25 ; length
       80 ; precedence=128
       83 ; D=1, relay type=3, a wire-encoded domain name
       09616d7472656c617973076578616d706c6503636f6d00 ) ; domain name

Notes
-----
In the first example, the IPv6 address is incorrectly encoded.

In the second example, the trailing root label of the domain name was not included, and should be.  This also increases the length by 1 byte.
