Add IPv6 support [2 XMR]

[shortwavesurfer2009]

Haveno does not recognize nodes on ipv6 such as feder8.me:18089 or [2607:3c40:1900:33e0::1]:18089

We discussed this topic in chat yesterday. Yes, IPv6 failed.
Mainnet-nodes for testing: 2a0b:f4c2:2::63:18081, 2a0b:f4c2:2:1::223:18081, 2001:4ba0:ffff:c4::2:18081
Stagenet: 2605:6400:30:f91d::2:38081

Comment from @fa2a5qj3:

Seems monero-wallet-rpc/cli does not work through Tor proxy to an IPv6 destination (IPv4 is ok).

Prerequisites:

• check ipv6 is supported with ping -6 feder8.me
• have tor daemon running

Tests:

1. start monero-wallet-rpc connecting to IPv4 node (node3.monerodevs.org:18089)
2. start monero-wallet-rpc connecting to IPv4 node (node3.monerodevs.org:18089) through SOCKS5 proxy
3. start monero-wallet-rpc connecting to IPv6 node (feder8.me:18089)
4. start monero-wallet-rpc connecting to IPv6 node (feder8.me:18089) through SOCKS5 proxy
5. start monero-wallet-rpc connecting to IPv6 node ([2a0b:f4c2:2::63]:18081)
6. start monero-wallet-rpc connecting to IPv6 node ([2a0b:f4c2:2::63]:18081) through SOCKS5 proxy

Tests 4 and 6 fail. I would have expected all 6 tests to pass.
The error message is "no_connection_to_daemon".

this is still an issue. I just tried my monerod over ipv6 with no luck. I can connect my cake wallet and mysu wallets to it just fine but cannot make haveno use it. I am using the restricted rpc port 18089 so am not sure if that has something to do with it or not

The issue will be resolved when monero-wallet-rpc supports SOCKS5.

@vtnerd said "I will put Socks5+IPv6 support in my next CCS proposal (hopefully I will have time for it)."

[shortwavesurfer2009]

Maybe a bit of a dumb question, but why do wallets like cake and mysu work with IPv6 nodes while this does not?

[boldsuck]

I think because of SOCKS5 support. Monero GUI and seednode to monerod works over IPv6.
