Add IPv6 support

[insomniacslk]

Dublin Traceroute is only able to work on IPv4 networks. IPv6 support is required, as IPv4 is a legacy protocol.

[insomniacslk]

current status: IPv6 support is present in the Go implementation but not yet in the C++ one

[marek22k]

Are there any news in the meantime?

[insomniacslk]

@marek22k no one has worked on IPv6 support in the C++ implementation. Meanwhile, if you need that, please use
the Go implementation

I apologize if my question came across as rude - that was not my intention.

How do I install or build the Go version?

$ go version
go version go1.19.8 linux/amd64
$ go install github.com/insomniacslk/dublin-traceroute@latest
go: github.com/insomniacslk/dublin-traceroute@latest: module github.com/insomniacslk/dublin-traceroute@latest found (v0.4.2), but does not contain package github.com/insomniacslk/dublin-traceroute
$ git clone https://github.com/insomniacslk/dublin-traceroute.git

Oh no worries, I didn't perceive it as rude.

go: errors parsing go.mod:
/home/marek/dublin-traceroute/go.mod:5: unknown directive: toolchain

This is due to the new directive toolchain introduced in Go 1.21.

You can either update your Go version to 1.21 or above, or try removing that line manually from go.mod in the root of the repository before you build. Let me know if that works

I have now tried it with a higher Go version:

$ go install github.com/insomniacslk/dublin-traceroute@latest
go: downloading github.com/insomniacslk/dublin-traceroute v0.4.2
go: github.com/insomniacslk/dublin-traceroute@latest: module github.com/insomniacslk/dublin-traceroute@latest found (v0.4.2), but does not contain package github.com/insomniacslk/dublin-traceroute
$ go version
go version go1.22.2 linux/amd64

[insomniacslk]

Oh, I'll have to fix that, I rarely use the go install route. Meanwhile can you try the following?

cd go/dublintraceroute/cmd/dublin-traceroute
go build
./dublin-traceroute --help

and let me know if that works for you?
