From 0ba98b12775b5394aab2205df29d93439d625cc3 Mon Sep 17 00:00:00 2001 From: Anubhav Shelat Date: Thu, 1 Jun 2023 16:27:35 -0400 Subject: [PATCH] Added code to check if the proc/net/if_inet6 file exists while loading IPv6 addresses in the IPv6Addresses class Added code to check if the proc/net/if_inet6 file exists while loading IPv6 addresses in the IPv6Addresses class. If it doesn't, then the system has IPv6 disabled, and that chunk of code is passed.
