VTL: Fix issue with ipaddress library use under python2.
If you pass in a non-unicode 4-byte ipv6 address to ip_address, ipaddress interprets this as an IPv4Address. Under python2, ip_address interprets 'a7::' as a packed ipv4: 97.55.58.58 You can test with: --- import ipaddress try: text_type = unicode except NameError: text_type = str addr = ipaddress.ip_address('a7::') print(addr) --- Change-Id: I06c561e0ab7315869cc89d0bb08c05e743a90982 Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
