- ryandrake 8y agoMind sharing an example? Not that I don’t believe you, but I’m fully IPV6 on my (admittedly small) home LAN and have IPV6 upstream to my ISP (thank you, Comcast), and everything I need works well. I’d love to know what you had trouble with, simply to verify for myself that I’m not unknowingly broken!
- wvenable 8y agoI'm sure it's highly dependent on the equipment. My ISP's router allows you to control the DNS settings for IPv4 but not for IPv6. So I could not reliably re-point the DNS servers. The router also gives the ability add local DNS names for lan addresses and that literally just doesn't work when IPv6 is enabled. Connecting to a Chromecast from iOS devices was also more hit and miss when IPv6 was enabled. Actually iOS devices seem to have a lot of LAN connectivity issues in general even though they had full access to the Internet. Again, this could be a router issue.
- mitchty 8y agoI also have had no issues with a fully dual stack ipv4 and ipv6 network on Comcast. I however do run my own firewall/router, its just a silly openbsd box with some pf firewall rules. I wouldn't trust any vendor router anyway. Never had issues with ipv6 internally with ios devices either. They're some of the most active ipv6 devices as well with the happy eyeballs or whatever change they seem to prefer ipv6.
- wvenable 8y agoI previously didn't have any choice but to use the ISP's router but I recently got fiber and now I'm no longer limited to the router they provide. I might splurge and buy a good one. I used to run my own PC-based router a long time ago but when it became impossible to use with my ISP I dropped it.
