Poor Man's DNS

Does your work computer not have it's own DNS name?
Does your work computer constantly change it's IP address?
Does this make working at home a pain for you?

If you said 'yes' to all of the above, then poor man's DNS is for you! Just schedule this ~20 line python script to run more often than your IP changes and get notified by email of all of your machine's IP addresses.
