is ip protocol reliable or unreliable?
15864
IP is a unreliable protocol because it does not guarantee the delivery of a datagram to its destination. The reliability must be provided by the upper layer protocols like TCP. IP does not support flow control, retransmission, acknowledgement and error recovery.

No, IP and IPv4 are not same because IPv4(internet protocol version 4) is a part of IP(internet Protocol). Two versions of the Internet Protocol are in common use in the Internet today. ... An IP address in IPv4 is 32-bits in size, which limits the address space to 4294967296 (232) IP addresses.

The IP protocol deals only with packets, and TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

The general consensus (which I agree with having set up many VPNs over the years) is that for reliable site to site VPN, one end must be a static IP address. For a remote access VPN (on demand, not full time, not site to site) a dynamic IP address at both ends can work well with a dynamic DNS service (e.g. noip.com).

Anything over 2% packet loss over a period of time is a strong indicator of problems. Most internet protocols can correct for some packet loss, so you really shouldn't expect to see a lot of impact from packet loss until that loss starts to approach 5% and higher.

TLS does not require TCP, it only requires a reliable transport. There is even a standard for TLS over SCTP which is another reliable transport protocol. But, if you take today's internet then you usually only have UDP and TCP as transport protocols on top of IP and from these two TCP is the only reliable one.

UDP (User Datagram Protocol) is a communications protocol that is primarily used for establishing low-latency and loss-tolerating connections between applications on the internet.

TCP is responsible for addressing packets and sending them on the correct route to the destination, while IP is responsible for reliable packet transmission.

Full cone NAT sticks a public address onto a LAN IP which would help for your individual device having problems but probably isn't the best thing to do from a security point of view.

Packet Loss. Packet loss is almost always bad when it occurs at the final destination. ... Most internet protocols can correct for some packet loss, so you really shouldn't expect to see a lot of impact from packet loss until that loss starts to approach 5% and higher.

['1) UDP is much faster. TCP is slow as it requires 3-way handshake. ... ', '2) DNS requests are generally very small and fit well within UDP segments.', '2) UDP is not reliable, but reliability can added on application layer. An application can use UDP and can be reliable by using a timeout and resend at the application layer.']

In short, TCP is reliable and guaranteed but UDP is not guaranteed. ... TCP provides ordering guaranteed which means the message will be received in the same order they are sent, UDP protocol doesn't provide such guarantee. TCP is a connection-oriented protocol as compared to UDP which is connectionless.

There are two types of Internet Protocol (IP) traffic. They are TCP or Transmission Control Protocol and UDP or User Datagram Protocol. TCP is connection oriented – once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol.

There are less than 4.2 billion available IPv4 IP addresses. In other words, there are more connected devices on the planet than there are unique, public IP addresses for them.

User Datagram Protocol (UDP) The basic unit of data is a User datagram and the UDP protocol provides the same unreliable, connectionless service transferring user datagrams as the IP protocol does transferring its datagrams. The main difference is that the UDP protocol is an end-to-end protocol.
