Basically Anvil is failing to resolve IPV6 addresses and when being ran in certain CI envs it fails

Correction: It is not anvil failing to resolve ipv6. It is cannon code that resolves server ip.

server.on('listening', () => {
  const addrInfo = server.address() as { address: string; family: 'IPv4' | 'IPv6'; port: number };
  resolve(`http://${addrInfo.family === 'IPv6' ? '[' + addrInfo.address + ']' : addrInfo.address}:${addrInfo.port}`);
});

@mjlescano any reference to PR/commit?

I have checked main branch and exact code is still there.
This is a blocker issue to use on CircleCI

in packages/cli/src/rpc.ts

    server.on('listening', () => {
      const addrInfo = server.address() as { address: string; family: 'IPv4' | 'IPv6'; port: number };
      resolve(`http://${addrInfo.family === 'IPv6' ? '[' + addrInfo.address + ']' : addrInfo.address}:${addrInfo.port}`);
    });
