If the sum of suffix length of IPv4 prefix and PSID length is bigger than EA bits length the domain is created.
If IPv4 packet is sent, then IPv6 destination address contains bits writen with PSID over the EA-bit length

Accepted MAP domain configuration:

• IPv6 src: 2001:db8:ffff::1
• IPv6 prefix: 2001:db8::/32
• IPv4 prefix: 20.169.0.0/16
• EA bits length: 20
• PSID length: 8
• PSID offset: 6

IPv4 packet sent:

• IP dst: 20.169.201.219
• UDP dst: 1232

Received IPv6:

• 2001:db8:c9db:3400:0:14a9:c9db:34
  green: EA bits, length 20
  red: overwriten bits
