            Bug ID: 16123
           Summary: DHCP supports _ in names thought the DNS does not -
                    very easy to fix
           Product: Busybox
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Networking
          Assignee: unassigned at busybox.net
          Reporter: busybox at bob.ma
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

When I use Hubitat, which is built on Busybox, I find that many devices have _
in their DHCP names. This is a major problem since I can't use the names for
devices like Wiz bulbs and must rely on the IP address which can change. One
example is "wiz_77cd58"

The simple fix is to just allow _ and if the DNS is built on DHCP it will work
and if not then it will fail but cause no harm.
