1st relay admin (any type dnot matter) can always SEE exit IP of the client
If I write and read everything over my mailboxes, then nobody else gets my IP or do nostr:nprofile1qy88wumn8ghj7mn0wvhxcmmv9uq3zamnwvaz7tmwdaehgu3wwa5kuef0qydhwumn8ghj7argv4nx7un9wd6zumn0wd68yvfwvdhk6tcqyp7vx29q3hdj4l0elxl800hlfjp538le09epsf7k9zj59ue2y37qurn3cw8 and nostr:nprofile1qyghwumn8ghj7mn0wd68ytnhd9hx2tcpr9mhxue69uhhwetvvdhk6efwdehhxarj9emkjmn99uq3wamnwvaz7tmfde3x77pwdehhxarj9emkjmn99uqzq0vy9tlv6h3f8u5tvcnexdcy50acec2n42ga0y9tz8m2w5k5ffpd7zaucw have to pass that info on?
And any web client gets it, I suppose, so @hodlbod and nostr:nprofile1qyfhwumn8ghj7ur4wfcxcetsv9njuetn9uq3samnwvaz7tmxd9k8getj9ehx7um5wgh8w6twv5hsz9mhwden5te0wfjkccte9ehx7um5wghxyctwvshsz9thwden5te0wfjkccte9ejxzmt4wvhxjme0qy28wumn8ghj7un9d3shjctzd3jjummjvuhszxmhwden5te0w35x2en0wfjhxapwdehhxarjxyhxxmmd9uqzq9eemymaerqvwdc25f6ctyuvzx0zt3qld3zp5hf5cmfc2qlrzdh08ca8zv and nostr:nprofile1qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qgwwaehxw309ahx7uewd3hkctcpzamhxue69uhhyetvv9ujumn0wd68ytnzv9hxgtcqyzsq3hh327t0h2dq6matqn5064cgj2zanl2stkj6s0lg4t2h5dty65pm0vv
What about Android clients? Does Freerse get my IP address nostr:nprofile1qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qg5waehxw309aex2mrp09skymr99ehhyee0qyv8wumn8ghj7enfd36x2u3wdehhxarj9emkjmn99uq3zamnwvaz7tmwdaehgu3wwa5kuef0qydhwumn8ghj7argv4nx7un9wd6zumn0wd68yvfwvdhk6tcpzdmhxue69uhhqatjwpkx2urpvuhx2ue0qqs9z3873rl5y57xgz8w3888ltn02qwcgkvmck73gq2dprjgjkrattcgemw5v ?
Who all is getting it?

I'm actually okay with them seeing it.
I don't want "random nutjob who wants to find my house" to see it, by putting up a bogus relay and collecting IPs over blastr.
Just like any webserver, the relays can see the IP. Clients too, if the client is a webserver. And then the 3rd thing that you may be more concerned with is when a client auto-loads a link or image from a note, as those can be more of a targeted attack to collect your IP via you looking at a note or DM.
correct - this is what the WhiteHAT guy did few months ago doxed geoip of many in realtime - just to demo. Also any CROSS-LINK to CDN server can see who is loading image/video - this has nothign to do with nostr. only TEXT notes are covered in this topic
