# Based on a script found on the Internet.Will add attribution if I find it.
# Changed 20150719 by Graeme Ruthven (graeme@kula.co.nz)
# Modified to:
# - update using authentication in URL as original method appeared to stop working.
# This was about the time of the RouterOS 6.30 release, but may be unrelated.
# - Get the previous IP from the contents of the dyndns.txt file, as the global variable
# doesn't appear to persist.
