I could ask the same question of you when you said "Another possibility to look for might be some wrongly configured IPv6 option somewhere, either on the laptop or the network".
The only thing that might be an issue is if IPv6 is enabled on the local network, but there is no IPv6 connection to the Internet. In that instance, a app might receive an AAAA record from the DNS and try to access the IPv6 address, even though it can't be reached. So first you poo-poo the possibility of it being an IPV6 issue, then you cite a VERY COMMON problem, where the router has IPV6 upstream but not downstream. This came to your mind because 2 or 3 years ago this was a major problem.
Does the OP have IPv6 enabled? If not, then it's not an issue. Enabling IPv6, beyond link local, requires deliberate action, such as configuring IP addresses by some means, setting up a router that the computer knows about etc.
By default, computers will have a link local (starts with fe80) IPv6 address, but that does not imply access beyond the local network and so would not cause the problem.
Regardless, that's a simple matter to determine. Look at the DNS replies with Wireshark. Do you see any AAAA records? If not, IPv6 will never be attempted. Look at the requests. A device on an IPv4 only network will not even request an AAAA record. Without receiving an IPv6 address, a device will not experience problems due to IPv6, as everything it does will be on IPv4.
As I said you need proper problem determination.
I don't know if IPv6 is enabled. However I let wireshark run a few seconds and have a lot of "AAAA" in the saved file, like for example: 39 16.232613990 9.9.9.9 10.0.0.2 DNS 168 Standard query response 0x342c AAAA assets.tumblr.com CNAME s.gycs.b.yahoodns.net AAAA 2a00:1288:7c:800::4001 AAAA 2a00:1288:7c:800::4000 -- Daniel Bauer photographer Basel Barcelona https://www.patreon.com/danielbauer http://www.daniel-bauer.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
