Legacy networks don't support VPC network peering or private services access. Neither connection method affects the other. You can configure an instance to use private IP at instance creation time. You can also configure an existing instance to use private IP.

Configuring an existing instance to use private IP, or changing the network it's connected to, causes the instance to be restarted, resulting in a few minutes of downtime. Nature-based Solutions as an umbrella concept for ecosystem-related approaches In framing NbS and considering its applications, it is useful to think of it as an umbrella concept that covers a whole range of ecosystem-related approaches all of which address societal challenges.

Unicast addresses identify a single interface. Each unicast address consists of n bits for the prefix, and — n bits for the interface ID. Multicast addresses identify a set of interfaces.

Each multicast address consists of the first 8 bits of all 1s, a 4-bit flags field, a 4-bit scope field, and a bit group ID:. The first octet of 1s identifies the address as a multicast address. The flags field identifies whether the multicast address is a well-known address or a transient multicast address.

The scope field identifies the scope of the multicast address. The bit group ID identifies the multicast group. Similar to multicast addresses, anycast addresses identify a set of interfaces.

However, packets are sent to only one of the interfaces, not to all interfaces. Anycast addresses are allocated from the normal unicast address space and cannot be distinguished from a unicast address in format.

Therefore, each member of an anycast group must be configured to recognize certain addresses as anycast addresses. Addressing is the area where most of the differences between IP version 4 IPv4 and IPv6 exist, but the changes are largely about the ways in which addresses are implemented and used. IPv6 has a vastly larger address space than the impending exhausted IPv4 address space. Each extra bit given to an address doubles the size of the address space. IPv4 has been extended using techniques such as Network Address Translation NAT , which allows for ranges of private addresses to be represented by a single public address, and temporary address assignment.

Although useful, these techniques fall short of the requirements of novel applications and environments such as emerging wireless technologies, always-on environments, and Internet-based consumer appliances. In addition to the increased address space, IPv6 addresses differ from IPv4 addresses in the following ways:.

Includes a scope field that identifies the type of application that the address pertains to. Does not support broadcast addresses, but instead uses multicast addresses to broadcast a packet. All IPv6 addresses are bits long, written as 8 sections of 16 bits each. They are expressed in hexadecimal representation, so the sections range from 0 to FFFF. Sections are delimited by colons, and leading zeroes in each section may be omitted. If two or more consecutive sections have all zeroes, they can be collapsed to a double colon.

IPv6 addresses consist of 8 groups of bit hexadecimal values separated by colons :. IPv6 addresses have the following format:. Each aaaa is a bit hexadecimal value, and each a is a 4-bit hexadecimal value. Following is a sample IPv6 address:. You can compress bit groups of zeros to double colons :: as shown in the following example, but only once per address:. An IPv6 address prefix is a combination of an IPv6 prefix address and a prefix length.

The ipv6-prefix variable follows general IPv6 addressing rules. The prefix-length variable is a decimal value that indicates the number of contiguous, higher-order bits of the address that make up the network portion of the address. Changes in source AS and destination AS are not immediately reflected in exported flows. In configuration commands, the protocol family for IPv6 is named inet6.

In the configuration hierarchy, instances of inet6 are parallel to instances of inet , the protocol family for IPv4. In general, you configure inet6 settings and specify IPv6 addresses in parallel to inet settings and IPv4 addresses. On SRX Series devices, on configuring identical IPs on a single interface, you will not see a warning message; instead, you will see a syslog message.

Understanding IPv4 and IPv6 Protocol Family IPv4 addresses are bit numbers that are typically displayed in dotted decimal notation and contains two primary parts: the network prefix and the host number.

Understanding IPv4 Addressing IPv4 addresses are bit numbers that are typically displayed in dotted decimal notation. Each address class specifies a different number of bits for its network prefix and host number: Class A addresses use only the first byte octet to specify the network prefix, leaving 3 bytes to define individual host numbers. In binary format, with an x representing each bit in the host number, the three address classes can be represented as follows: xxxxxxxx xxxxxxxx xxxxxxxx Class A xxxxxxxx xxxxxxxx Class B xxxxxxxx Class C Because each bit x in a host number can have a 0 or 1 value, each represents a power of 2.

For example, if only 3 bits are available for specifying the host number, only the following host numbers are possible: In each IP address class, the number of host-number bits raised to the power of 2 indicates how many host numbers can be created for a particular network prefix. IPv4 Dotted Decimal Notation The bit IPv4 addresses are most often expressed in dotted decimal notation, in which each octet or byte is treated as a separate number.

IPv4 Subnetting Because of the physical and architectural limitations on the size of networks, you often must break large networks into smaller subnetworks. Figure 1: Subnets in a Network.
