Hello Busybox Team,

I build udhcpc with "ENABLE_FEATURE_UDHCPC_SANITIZEOPT" enabled.

If my client get a hostname prefix with a number udhcpc converts it to "bad".

in source code

http://git.busybox.net/busybox/tree/networking/udhcp/dhcpc.c
line 139 ff

there RFC1035 is refered but this is for domains only.
For hostnames RFC952 should by used. For internethosts RFC1123.
Both allow numbers as first character for hostnames.

kind regards
Hubenau
