Out of the box these home routers all come with the same subnet (every linksys out of box runs 192.168.1.0/24 in the US ). Private addressing behind the box is meaningless in the telecom cloud. It's all NAT.
Could be 10/8 used elsewhere for some other network but us infrastructure guys are lazy. NAT that shit. I've never known an ISP to be a monument to best practices.
I've yet to come across any 30/8 subnets in my career. RFC1918 gives one a shit-ton of address space to work with. Bleeding into the 30/8 for necessity seems like something is wrong somewhere.
The fact ipv6 isnt more widely adopted reiterates my point above, engineers are lazy and NAT works. I've only known one company to use public ipv4 space for managment and they were a mess. I'd love to say using 30/8 is out of necessity or out of laziness but it's just oddly convenient.
