Second address is technically incorrect. The loopback address subnet 127/8 does not contain private network addresses like 192.168/16, 172.16/12, or 10/8 and doesn't provide any utility for routing within the local network.

I use Altium Designer and KiCAD. KiCAD isn't as good by just a hair but makes up for it by being free and open-source. Altium Designer is also crazy expensive for hobbyists.
