| Domain name IP Dns-layer is not the same with Domain Name System (DNS). It is a protocol that governs domain name resolving operations. Domain Name System (DNS) is a trademark application that registers, manages and modifies top-level domain name extensions, as well as top-level DNS zones and names. In contrast, IP address is an unformatted, fixed set of numbers that uniquely identify IP addresses and their owners. The uniqueness of an IP address depends on the components that are used together with the zero, component, and network prefix length as defined by the IP standard. There are two types of domain name systems, Internet Domain Name System or DNS and the localized domain name system or L DNS. The difference between DNS and L DNS lies in the fact that DNS provides a uniform Resource Locality Information Format (RLS), while L DNS relies on the local information as defined by the Network Interface for resolving domain name queries. It also supports Uniform Resource Identifiers (UVIs) and names in lower case hexadecimal format. However, they are not interchangeable. An IP address, domain name, or web site address represents an entity on the Internet. To be precise, an IP address is a numerical representation that uniquely identifies a computer or entity on the network. An IP address can be represented in hexadecimal (h), octal (o), or binary (b) notation. The Internet Protocol (IP) addresses are used within an intranet application such as an email server or the World Wide Web itself. In the previous portion of this article, we presented an overview of the DNS, including an introduction to DNS, an introduction to the DNS server, and the DNS protocol. In section three, we presented an overview of IP address management and IP address using the Simple Network Management Protocol or SNMP. In section four, we introduced IP addressing, including an introduction to the IP address family and an introduction to the subnet. We discussed an example of an IP address, an IP route, and an IP forward error. In the next section, we presented a short overview of the IP layer and IP address management. We considered some of the challenges involved in IP layer discovery and IP scheduling. Then we discussed some typical IP packets and how they are used. We saw how an IP packet could be resolved or orphaned, and saw some typical use of the DNS and the IP addressing. We saw how an IP address could be delegated to a service and how this would affect the IP data packet and IP reply. In the last part of this article, we presented a description of some common DNS suffixes, the main DNS server, and the major part of the DNS protocol. Specifically, we looked at the main DNS server, the DNS suffix, the DNS name server, the TLDs, and IP addresses. We explained about the main advantages and disadvantages of using an internal or an externally derived DNS, and looked at some practical considerations for choosing DNS suffixes. We concluded by briefly describing the DNS protocols and the security properties that come with them. To conclude, we presented a brief introduction of DNS, including the basics of domain name registration, IP addressing and namespaced name registration. Specifically, we discussed DNS suffixes, DNS servers, and IP addresses. We looked at some typical IP packets and how they are used. Finally, we briefly discussed the security properties of DNS and IP addresses. We ended this article by briefly describing the DNS protocols and security properties that come with them. This was a brief explanation of DNS. It presented a simple overview of how people use DNS. It described IP addresses and the role of the DNS in hosting. It also introduced namespaced names and IP addresses. |
