Spam has become a daily nuisance for everybody. The number of spam e-mails can overwhelm our inboxes, reducing the space and chances for important messages to be received. Besides, they are a constant and real threat to our security. Scams, phishing attacks, malware can be attached to them, risking our personal information, business, and systems.
Fortunately, developers constantly improve and innovate with tools to defeat, or at least mitigate, these threats. DKIM is an example.
The DHCP is an excellent illustration of how technology influences our everyday life. Both network administrators and clients benefit from it. It automatically designates IP addresses to the connected devices. It also keeps the information about them, and after they run out, it reuses the IPs.
The acronym DHCP stands for Dynamic Host Configuration Protocol. It is a very effective solution for management and is commonly used on TCP/IP networks. Its work is to give IP addresses automatically and all the needed network configurations to connected devices to interact. The ones that benefit the most from DHCP are DNS servers, default gateway, subnet mask, and more.
Domain Name System (DNS) is a naming database system. It is locating and translating domain names into IP addresses. Imagine it is like a directory or even like a mobile’s contacts list. Each one of the names corresponds with numbers, and they are accurately matched. DNS directory is spread worldwide. This system operates daily. It helps to explore and reach millions of domain names every day. Without Domain Name System, we would have to remember each site’s IP address to visit it. This sounds nearly impossible, considering how many sites are out there.
