It just results in more complicated dns server list update function but it is still somehow solvable. Another solution is to have enough space in DNS server list so you can keep both. You can just configure this in lwipopt.h how many items you need to keep in memory. If you configure just 2 items, just don't count with full and correct RFC support.
This is out of my knowledge and imagination. |

Corresponding source code
I've pushed just pushed this, but I think we'll need to re-think dual-stack behaviour for DNS.
I've added task #14274 for that.
Thanks for the patch.
Oh, and sorry I missed setting you as committer after applying failed. But at least in CHANGELOG it's correct.
