Expand description

The possible errors of a GenDnsConfig wrapped transport.

Variants

`Transport(TErr)`

The underlying transport encountered an error.

`ResolveError(ResolveError)`

DNS resolution failed.

`MultiaddrNotSupported(Multiaddr)`

DNS resolution was successful, but the underlying transport refused the resolved address.

`TooManyLookups`

DNS resolution involved too many lookups.

DNS resolution on dialing performs up to 32 DNS lookups. If these are not sufficient to obtain a fully-resolved address, this error is returned and the DNS records for the domain(s) being dialed should be investigated.
