The inet address is your IP address. It is not one of the 3 private ip address ranges so it is a external IP that can be accessed for the outside.
If you have an IP inside the following ranges
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
Then the IP is behind a NAT, and cant be accessed from the outside without port forwarding of some kind setup. Since your IP is not in any of those ranges it is a public ip and can be accessed through the internet as long as the firewall in front of it is not explicitly blocking packets.
The Bcast address is the broadcast address of your subnet (the network that you are on), this IP is not assigned to to you alone and is the same for everyone on your subnet. A broadcast address is the last IP in a subnet, it is not assignable to any host but rather used by many networking protocols.
You can find out your hostname by running the
hostname command or
