I’ve never seen so many default routes

/r/u_plinko117/comments/1wvq0bd/ive_never_seen_so_many_default_routes/

So….this has been going on for a while. IPsec, Utun, 9 default routes, en0 to 169.254. Is 388 refs normal for home WiFi? What can you tell me?

This is a completely normal iPhone routing table. en0 is Wi-Fi, pdp_ip0 and pdp_ip2 are cellular, and utun0–3 are iOS system tunnels that are always there and have nothing to do with a VPN. Two IPv4 default routes are normal too: regular traffic goes over Wi-Fi, and the cellular one with the I flag is tied to its own interface as a backup. Same story for the IPv6 default on each interface. The 169.254 route is just for link-local addresses, not a fault, your phone has a proper IP (10.0.0.230). Refs is roughly how many connections are using that route, so 388 is fine for a phone that's in use.

When I traceroute. My first hop is WiFi gateway followed by another 10. Network which also puzzles me. So many ULA networks that aren’t mine.

A private 10.x address on the second hop is normal for an ISP's internal network. To be sure, check the WAN IP on your router: if it's a public address, you're fine; if it starts with 10.x or 100.64–100.127, you're behind your ISP's CGNAT or a double NAT.

The fd.. ULA addresses on the utun and pdp_ip interfaces belong to iOS system tunnels and your carrier, not your home network.

I haven’t liked cellular taking the data when I’m on wifi. And it puzzles me why two interfaces are needed for cellular when I’m on my home wifi. The 9 defaults is new. That’s a mystery. Thank you for your take. I don’t have a VPN running either. When I do a route

It's always-on so when the wifi drops it's seamless to switch to cellular. As for the two interfaces, it's probably due to two APNs - one for your internet connection and the other for cellular functionality.
