The IPv6 address logged at the startup like `::1:80` was wrong because the port isn't clearly separated. This commit corrects it, now logging as `[::1]:80`. This is done in accordance to RFC 3986. In short, we did this have a clear separation between the port and host because the components of an IPv6 are separated with the ':' character. Signed-off-by: Taimoor Zaeem <taimoorzaeem@gmail.com>
