# What is the issue
56+
57+
It works well, **except for some _small_ issues**:
58+
- **IPv4 literals** don't work (outside Chrome)
59+
- Legacy and/or **low-level apps** may not work well (eg. VirtualBox)
60+
61+
62+
# How are others solving this
63+
64+
- **Android:** There is in-device CLAT translating residual IPv4 to IPv6
65+
- **Apple:** App developers are forced **not to produce broken apps** and there is a CLAT as well
66+
- **Windows:** There is a CLAT but **only if you plug in an USB modem**

# What have we done
73+
74+
- A **daemon in Python** listening for PREF64 option in Router Advertisements
75+
- A **Go implementation** of RFC 7050 NAT64 prefix discovery
76+
- **Perl script** `clatd` adjusted to support `nat46` kernel module in place of `TAYGA`
77+
78+
# We are not done yet
79+
- There's still no comprehensive easy-to-use solution
80+
- We really need to convince the developers of `NetworkManager` and `systemd-networkd`
