Common utility sets supporting IPv6 and IPv4 can help router administrators test or troubleshoot network problems in some cases, such as `ndptool send` and `arping`, sending and detecting NDP, etc
I intend to use the following path:
```
ndp interface <interface> type <type>
discovery ipv6 ndisc6 interface <interface> ip <ip>
discovery ipv6 rdisc6 interface <interface> ip <ip>
discovery ipv4 arping interface <interface> destip <destip>
discovery ipv4 arping interface <interface> destip <destip> duplicate
discovery ipv4 arping interface <interface> destip <destip> no-unicast
discovery ipv4 arping interface <interface> destip <destip> no-unicast duplicate
discovery ipv4 arping interface <interface> sourceip <sourceip> destip <destip>
traceroute ipv4 <host> tcp port <port>
traceroute ipv6 <host> tcp port <port>
```
