Ipv6 Dns Name Unresolved From Ipv4 Network

I am having a strange problem which seems to be a problem of ipv6 vs ipv4 dns names. I have a real time scraper which runs on my server which runs on ipv6 network. After scraping,

Solution 1:

Obviously img-ipv6.flixcart.com is supposed to resolve only to an IPv6 address, not to a v4 one: it just has the IPv6 address 2001:df0:23e:9002::17 which you clearly cannot access from your PC.

Over a IPv4 connection, the image has the address http://img7.flixcart.com/image/book/8/7/5/it-s-not-about-the-bike-my-journey-back-to-life-275x275-imadarucmnec3hds.jpeg.

Solution 2:

The server name img-ipv6.flixcart.com only has an IPv6 address. It does not have an IPv4 address.

You will only be able to access that hostname on servers that have IPv6 connectivity.
