FQDN?

[Gary Turner <kk5st@swbell.net>]

For whatever reason, I just can't wrap my mind around this for my setup.

What I have is:

Netgear gateway/router/firewall which also handles chat with ISP to
maintain connection negotiate dynamic IP (bessie)

Workstations are etta, aretha, hattie (win), and koko (lin).

The workgroup is blues.

My ISP/mail username is kk5st

My news server username is kk5st@swbell.net

I do not have a registered domain name, nor static IP.  So how are the
FQDN's constructed?

tnx,
