58.12 Dynamic Host Name Mapping
A number of providers supply free Dynamic DNS services whereby a home user connecting through an ISP with dynamic IP addresses (the IP address changes on each new connection) can associate a host name with the IP address. This is like controlling a moving target, and works very well.
You can find your current IP address with:
lynx -dump http://checkip.dyndns.org \ | sed -n '/Current/s/.*: \([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\)/\1/p'
