# iface eth0 inet static
# address 190.168.23.175
# netmask 255.255.255.240
# dns-nameservers 8.8.8.8 8.8.4.4
# up ip -4 route add default via 169.254.0.1 dev eth0 onlink
#
# The netmask tells the total number of IP in the network is only 15(240 - 255),
# but we obsessed that there are more than 15 IPv4 addresses between 169.254.0.1 and 190.168.23.175 clearly.
# So if netmask is 255.255.255.240(prefix is 28), the computer only find IP between 190.168.23.160 and 190.168.23.175,
# the gateway 169.254.0.1 is obviously not be included in this range.
# So we need to expand the range of the netmask(reduce the value number of the prefix) to make sure the IPv4 gateway can be contained.
# If this mistake has not be repaired, Debian installer will return error "untouchable gateway".
# DHCP IPv4 network(even IPv4 netmask is "32") may not be effected by this situation.

# up ip -f inet route add 169.254.0.1 dev ens3
# up ip -f inet route add default via 169.254.0.1 dev ens3

# The A class of address and gateway are entirely different, although we should make sure the value of the suggested subnet mask is "128.0.0.1"(prefix "1")

# can't be included, so the reserve approach is to get the result of "ip -4 route show scope link"(89.163.208.0/24) to ensure the correct subnet and gateway,

# The value of mask must be set as "128", not "1" which determined by first condition of above because the local IPv6 address is unique in its' network
# and plays the role of IPv6 network discovery and identical authentication to ensure that authenticated device is certificated by upstream.
# Explanation of using local IPv6 address as gateway quoted from Scott Hogg:
#
# Link-local IPv6 addresses are on every interface of every IPv6-enabled host and router. They are essential for LAN-based Neighbor Discovery communication.
# After the host has gone through the Duplicate Address Detection (DAD) process ensuring that its link-local address (and associated IID) is unique on the LAN segment,
# it then proceeds to sending an ICMPv6 Router Solicitation (RS) message sourced from that address.
#
# There are total three IPv6 address ranges divided into local address: fe80::/10, fec0::/10, fc00::/7.
# "fe80::/10" is similar with "169.254.0.0/16" of IPv4 of February, 2006 according to RFC 4291, ranges from fe80:0000:0000:0000:0000:0000:0000:0000 to febf:ffff:ffff:ffff:ffff:ffff:ffff:ffff.
# "fec0::/10" is similar with "192.168.0.0/16" of IPv4 which was deprecated and returned to public IPv6 address again of September, 2004 according to RFC 3879.
# The function of "fec0::/10" was replaced by "fc00::/7" of October, 2005 according to RFC 4193, ranges from fc00:0000:0000:0000:0000:0000:0000:0000 to fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff.
# So we need to calculate ranges of "fe80::/10" and "fc00::/7", if IPv6 address is public and IPv6 gateway belongs to local IPv6 address.
# English strings in hexadecimal must be converted as capital alphabets that comparison operations can be processed by shell.

# gateway 59.67.82.1
# netmask 255.255.255.0

# up ip addr add 2a12:a520:d420::736f/48 dev eth0
# up ip addr add 2a12:a520:2e0b::a89c:11de/40 dev eth0
# up ip -6 route add 2a12:a520:2e0b:0000:0000:0000:0000:0001 dev eth0
# up ip -6 route add default via 2a12:a520:2e0b:0000:0000:0000:0000:0001 dev eth0
#
# A standard format of adding multiple IPv6 configs into IPv6 stack server for Debian series:
#
# allow-hotplug enp3s0
# iface enp3s0 inet6 static
# address 2606:a8c0:3::64/128
# gateway 2606:a8c0:3::1
# dns-nameservers 2606:4700:4700::1001 2001:4860:4860::8844

# up ip addr add 2606:a8c0:3:6f::3b/64 dev enp3s0
# up ip addr add 2606:a8c0:3:6f::a/64 dev enp3s0
#
# A standard formart of adding multiple IPv6 addresses for the second network adapter in Bi-stack(dual-stack) server for Debian series:
# The first network adapter which is called such as "eth0" plays a role of establishing IPv4 stack network,
# and then the second network adapter of "eth1" is responsible of creating multiple terms of IPv6 stack networking configurations.
# This uncommon and extreme situation can only be applied for Debian series at current because the file of "/etc/network/interfaces" is easily to be modified.
#
# allow-hotplug eth0

# The most typical case is when you search these fuckin files by "grub", the result deleted two single quotes automatically like:
#
# [root@instance-2 ~]# grep -r "ipv4" /run/NetworkManager/system-connections/
# /run/NetworkManager/system-connections/Wired connection 1.nmconnection:[ipv4]

# [root@instance-2 ~]# ls /run/NetworkManager/system-connections/ | head -n 1 | tail -n 1
