It seems you get your address by DHCP from Comcast, and their DHCP 
server instructs the DHCP client to change your hostname, the same way 
that it can set your client DNS server address to use for example.

If your dhcp client app is dhclient

ps -Af | grep dhclient

which it is IIRC for Fedora, you can use a supersede keyword to defeat 
the dhcp server from changing your locally preferred value.  See

man dhclient.conf

Or another way to come at it is to mess with

/etc/bashrc

if you don't mind the fact your hostname changed but just want to 
control the bash prompt.
