By Parija Kavilanz, CNN. Kristen Rogers, CNN. Given COD's continued non-appearance on Game Pass, you've got to imagine the restrictions are fairly significant if they're not an outright block on COD coming to the service. Either way, the simple fact that Microsoft is apparently willing to maintain any restrictions on its own ability to put first-party games on Game Pass is rather remarkable, given that making Game Pass more appealing is one of the reasons for its acquisition spree.
The irony of Sony making deals like this one while fretting about COD's future on PlayStation probably isn't lost on Microsoft's lawyers, which is no doubt part of why they brought it up to the CMA. While it's absolutely reasonable to worry about a world in which more and more properties are concentrated in the hands of singular, giant megacorps, it does look a bit odd if you're complaining about losing access to games while stopping them from joining competing services.
We'll find out if the CMA agrees when it completes its in-depth, "Phase 2" investigation opens in new tab into the Activision Blizzard acquisition, which is some way off yet. For now, we'll have to content ourselves with poring over these kinds of corporate submissions for more interesting tidbits like this one.
So far, we've already learned that Microsoft privately has a gloomy forecast for the future of cloud gaming opens in new tab , and that the company thinks Sony shouldn't worry so much since, hey, future COD games might be as underwhelming as Vanguard opens in new tab.

Internet Protocol version 4 IPv4 is the fourth version of the Internet Protocol IP. It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production on SATNET in and on the ARPANET in January It is still used to route most Internet traffic today,  even with the ongoing deployment of Internet Protocol version 6 IPv6 ,  its successor.
IPv4 uses a bit address space which provides 4,,, 2 32 unique addresses, but large blocks are reserved for special networking purposes. Internet Protocol version 4 is described in IETF publication RFC September , replacing an earlier definition of January RFC The Internet Protocol is the protocol that defines and enables internetworking at the internet layer of the Internet Protocol Suite.
In essence it forms the Internet. It uses a logical addressing system and performs routing , which is the forwarding of packets from a source host to the next router that is one hop closer to the intended destination host on another network.
IPv4 is a connectionless protocol, and operates on a best-effort delivery model, in that it does not guarantee delivery, nor does it assure proper sequencing or avoidance of duplicate delivery. These aspects, including data integrity, are addressed by an upper layer transport protocol, such as the Transmission Control Protocol TCP. IPv4 uses bit addresses which limits the address space to 4 2 32 addresses.
IPv4 reserves special address blocks for private networks ~18 million addresses and multicast addresses ~ million addresses. IPv4 addresses may be represented in any notation expressing a bit integer value.
They are most often written in dot-decimal notation , which consists of four octets of the address expressed individually in decimal numbers and separated by periods.
For example, the quad-dotted IP address Other address representations were in common use when classful networking was practiced. For example, the loopback address When fewer than four numbers are specified in the address in dotted notation, the last value is treated as an integer of as many bytes as are required to fill out the address to four octets. Thus, the address In the original design of IPv4, an IP address was divided into two parts: the network identifier was the most significant octet of the address, and the host identifier was the rest of the address.
The latter was also called the rest field. This structure permitted a maximum of network identifiers, which was quickly found to be inadequate. To overcome this limit, the most-significant address octet was redefined in to create network classes , in a system which later became known as classful networking.
The revised system defined five classes. Classes A, B, and C had different bit lengths for network identification. The rest of the address was used as previously to identify a host within a network.
Because of the different sizes of fields in different classes, each network class had a different capacity for addressing hosts. In addition to the three classes for addressing hosts, Class D was defined for multicast addressing and Class E was reserved for future applications. Dividing existing classful networks into subnets began in with the publication of RFC This division was made more flexible with the introduction of variable-length subnet masks VLSM in RFC in CIDR was designed to permit repartitioning of any address space so that smaller or larger blocks of addresses could be allocated to users.
The hierarchical structure created by CIDR is managed by the Internet Assigned Numbers Authority IANA and the regional Internet registries RIRs. Each RIR maintains a publicly searchable WHOIS database that provides information about IP address assignments. The Internet Engineering Task Force IETF and IANA have restricted from general use various reserved IP addresses for special purposes. Of the approximately four billion addresses defined in IPv4, about 18 million addresses in three ranges are reserved for use in private networks.
Packets addresses in these ranges are not routable in the public Internet; they are ignored by all public routers.
Therefore, private hosts cannot directly communicate with public networks, but require network address translation at a routing gateway for this purpose. Since two private networks, e. Additionally, encapsulated packets may be encrypted for transmission across public networks to secure the data.
RFC defines the special address block These addresses are only valid on the link such as a local network segment or point-to-point connection directly connected to a host that uses them. These addresses are not routable. Like private addresses, these addresses cannot be the source or destination of packets traversing the internet.
These addresses are primarily used for address autoconfiguration Zeroconf when a host cannot obtain an IP address from a DHCP server or other internal configuration methods. When the address block was reserved, no standards existed for address autoconfiguration. Microsoft created an implementation called Automatic Private IP Addressing APIPA , which was deployed on millions of machines and became a de facto standard.
Many years later, in May , the IETF defined a formal standard in RFC , entitled Dynamic Configuration of IPv4 Link-Local Addresses. The class A network IP packets whose source addresses belong to this network should never appear outside a host. Packets received on a non-loopback interface with a loopback source or destination address must be dropped.
The first address in a subnet is used to identify the subnet itself. In this address all host bits are 0. To avoid ambiguity in representation, this address is reserved. It is used as a local broadcast address for sending messages to all devices on the subnet simultaneously.
For example, in the subnet The broadcast address of the network is However, this does not mean that every address ending in 0 or cannot be used as a host address. One can use the following addresses for hosts, even though they end with Also, In the past, conflict between network addresses and broadcast addresses arose because some software used non-standard broadcast addresses with zeros instead of ones. For example, a CIDR subnet These networks are typically used for point-to-point connections.
There is no network identifier or broadcast address for these networks. Hosts on the Internet are usually known by names, e. com, not primarily by their IP address, which is used for routing and network interface identification. The use of domain names requires translating, called resolving , them to addresses and vice versa.
This is analogous to looking up a phone number in a phone book using the recipient's name. The translation between addresses and domain names is performed by the Domain Name System DNS , a hierarchical, distributed naming system that allows for the subdelegation of namespaces to other DNS servers. A unnumbered point-to-point PtP link, also called a transit link, is a link that doesn't have an IP network or subnet number associated with it, but still has an IP address.
First introduced in ,      Phil Karn from Qualcomm is credited as the original designer. The purpose of a transit link is to route datagrams. They are used to free IP addresses from a scarce IP address space or to reduce the management of assigning IP and configuration of interfaces. When a link is unnumbered, a router-id is used, a single IP address borrowed from a defined normally a loopback interface. The same router-id can be used on multiple interfaces. One of the disadvantages of unnumbered interfaces is that it is harder to do remote testing and management.
In the s, it became apparent that the pool of available IPv4 addresses was depleting at a rate that was not initially anticipated in the original design of the network. In addition, high-speed Internet access was based on always-on devices. The threat of exhaustion motivated the introduction of a number of remedial technologies, such as:.
By the mids, network address translation NAT was used pervasively in network access provider systems, along with strict usage-based allocation policies at the regional and local Internet registries. The primary address pool of the Internet, maintained by IANA, was exhausted on 3 February , when the last five blocks were allocated to the five RIRs.
The long-term solution to address exhaustion was the specification of a new version of the Internet Protocol, IPv6. However, IPv4 is not directly interoperable with IPv6, so that IPv4-only hosts cannot directly communicate with IPv6-only hosts. With the phase-out of the 6bone experimental network starting in , permanent formal deployment of IPv6 commenced in An IP packet consists of a header section and a data section. An IP packet has no data checksum or any other footer after the data section.
Typically the link layer encapsulates IP packets in frames with a CRC footer that detects most errors, many transport-layer protocols carried by IP also have their own error checking. The IPv4 packet header consists of 14 fields, of which 13 are required. The 14th field is optional and aptly named: options. The fields in the header are packed with the most significant byte first big endian , and for the diagram and discussion, the most significant bits are considered to come first MSB 0 bit numbering.
The most significant bit is numbered 0, so the version field is actually found in the four most significant bits of the first byte, for example. The packet payload is not included in the checksum.
Its contents are interpreted based on the value of the Protocol header field. List of IP protocol numbers contains a complete list of payload protocol types. Some of the common payload protocols include:. The Internet Protocol enables traffic between networks. The design accommodates networks of diverse physical nature; it is independent of the underlying transmission technology used in the link layer.
Networks with different hardware usually vary not only in transmission speed, but also in the maximum transmission unit MTU. When one network wants to transmit datagrams to a network with a smaller MTU, it may fragment its datagrams.
