Pretty normal (especially after restart).

Odd, but likely harmless. Should be looked into though.

Can you 'wget' those? Again, could happen, but shouldn't happen too much.

IPv4 addresses, looks like for some reason you were trying to route IPv4
traffic via GNUnet, and GNUnet didn't find a suitable EXIT node (quite
plausible that none is even available right now) so it couldn't deliver
the packets.

Those are new to me, should be looked at. => #3894.

Also new to me => #3895.  It would be good to know exactly which
revision those came from as CADET has evolved rapidly in the last week.

Were libcurl/libgnurl found by configure? If not, you somehow configured
those plugins but they were not compiled (or installed properly).

That one is well-known (#3863), a performance issue we yet have to
investigate, but not fatal (except highly annoying for voice apps).
