I made a change today to my DNS settings for mazyod.com, and whenever I run:
$ dig mazyod.com
I am seeing the old IP address!! I got sick of waiting and trying every now and then, so I open terminal and script it:
>>> import time
>>> import subprocess as sp
>>>
>>> time.sleep(1)
>>> while 1:
... time.sleep(10)
... IP = '184.168.221.12'
... process = sp.Popen(['dig', 'mazyod.com'], stdout=sp.PIPE)
... output, something = process.communicate()
...
... if IP not in output:
... print 'YAAAY'
... break
... else:
... print 'no.. '+output
...
I literally go to the bathroom, and come back to find the output:
YAAAY
… Took exactly 3 tries before the DNS updated. That’s 3 tries multiplied by 10 second intervals between them tries…
