>Description:
Some macros below are defined in sys/netinet6/icmp6.c.
#define isupper(x) ('A' <= (x) && (x) <= 'Z')
#define isalpha(x) (('A' <= (x) && (x) <= 'Z') || ('a' <= (x) && (x) <= 'z'))
#define isalnum(x) (isalpha(x) || ('0' <= (x) && (x) <= '9'))
#define tolower(x) (isupper(x) ? (x) + 'a' - 'A' : (x))

And func ni_nametodns() uses them by way of tolower(*p++),
so it becomes (isupper(*p++) ? (*p++) + 'a' - 'A' : (*p++)).

>How-To-Repeat:
Set hostname like mine.
Or just hit 'ping6 -w 3ffe:501:100c:d210:2e0:81ff:fe04:3727'
