Well i blocked sun.hac.lp1.d4c.nintendo.net in my router and it still updated.
Try ping sun.hac.lp1.d4c.nintendo.net from your computer and see if the router does block it
Some routers URL filtering function (such as mine) just don't work

If you want to block everything then here:

NOTE: These URLs are encrypted hence port 443. Some consumer routers do not let you enter a port in your blocking interface you may have to use HTTPS:// instead.

http://aqua.hac.lp1.d4c.nintendo.net:443
http://sun.hac.lp1.d4c.nintendo.net:443
http://receive-lp1.dg.srv.nintendo.net:443
http://bcat-data-lp1.cdn.nintendo.net:443
http://bcat-list-lp1.cdn.nintendo.net:443
http://tagaya.hac.lp1.eshop.nintendo.net:443
http://dauth-lp1.ndas.srv.nintendo.net:443

EDIT: URLs related to eshop, how did google get in there those sneaky buggers!

http://bugyo.hac.lp1.eshop.nintendo.net:443
http://accounts.nintendo.com:443
http://www.google-analytics.com:443
http://ecs-lp1.hac.shop.nintendo.net:443

If you want to just block the nag screen and update server use this one:

http://sun.hac.lp1.d4c.nintendo.net:443

Disclaimer: URLs are subject to change, I will not be held responsible if nintendo suddenly starts using, for eg. deathstar.hac.lp1.d4c.nintendo.net for updates. Also some of those addresses seem region specific cdn.nintendo.net. Your mileage may vary.
I could be wrong but I think there are two receive URLs that @DocAmes1980 brought up

I'm not sure that's how it works on the Switch. I've been using a DNS emulator to resolve "sun.hac.lp1.d4c.nintendo.net" to NXDOMAIN for about a week now. I've also been blocking "receive-lp1.dg.srv.nintendo.net" and "receive-lp1.er.srv.nintendo.net" as they appear to be for telemetry and error reporting respectively. I'm not blocking "tagaya.hac.lp1.eshop.nintendo.net". Manually checking for updates fails as well as automatic updates. I'm still on 2.0.0 and have seen no nag screen. Also, game updates work as expected. There is a curiosity though. I didn't pay close attention to traffic before the 2.1.0 update went live but I noticed the Switch checked for updates (attempted to connect to sun.hac.lp1.d4c.nintendo.net) somewhat infrequently. A day after the 2.1.0 update came out I checked traffic and noticed it was attempting to contact "sun.hac.lp1.d4c.nintendo.net" every minute. I wonder if after it fails to contact the update server after X number of days it starts to check every minute. If the Switch was aware of a newer version I'd think I would be presented with the nag screen.
How come you leave tagaya url unblocked? Which is that for exactly.

I suggest everyone block this one too:
http://receive-lp1.er.srv.nintendo.net:443

Every Time the update server is blocked it phones home and reports the error. No sense giving Ninty anymore info than they need.

Also although I was able to block the game update server http://superfly.hac.lp1.d4c.nintendo.net:443 from updating snake pass, I could not get rid of the nag.

I will now let it update, that patch fixes the annoying rumble bug.

--------------------- MERGED ---------------------------

I'll add them and credit you too. Thank you sir.
No, thank you. I do things for the greater good, and I help people because I like to help and problem solve. People don't usually even say "thanks".

You just made my day. It's the small things in life...

Absolutely. I'd also look into "receive-lp1.dg.srv.nintendo.net". When I first changed my DNS settings to use my DNS emulator I instantly noticed that whenever I selected damn near anything from the system interface it would phone home to that domain name. I only watched it for a brief time because I blocked it and "receive-lp1.er.srv.nintendo.net " right away. Since I blocked "...dg..." it only attempts to send info to the mothership every once and a while. I'm not unblocking it to what N. I don't want Nintendo to put a case on me.

Crap router from my ISP

Manufacturer:FiberHome;
ProductClass:AN5506-04-F
Be sure your firewall is enabled.

Then on the filter screen click enable, make sure blacklist is selected, then click apply.

Click add, then enter this:

sun.hac.lp1.d4c.nintendo.net

Why shouldn't we update? I mean, there won't be a hack anytime soon, and when theres a hack in the future, it will be most likely executable on newer firmwares.
