Hi Sumit, Interestingly, this error comes from python-netaddr module. Could you find out the version that you are using? I haven't had any problem with 0.7.4 so you might want to try that out.
Someone seems to have already raised this issue: https://github.com/drkjam/netaddr/issues/10 Let me know if you still see this using a different version of netaddr. cheers, Ryu On Wed, Jul 20, 2011 at
