Performance starts with DNS. Every connection your phone, laptop or tablet uses to collect information starts with a DNS connection. Catchpoint collaborated with IBM to measure the speed of DNS connections to over 2,000 of the most visited websites and compare the performance across DNS providers – and the results were surprising! We give you all the details in our new, comprehensive global DNS performance report, “The need for speed: Why you should give your network’s DNS performance a closer look.” Get the full report and uncover all the details (no registration needed): https://lnkd.in/gCeeVRWZ #DNSperformance #DNS #InternetPerformanceMonitoring #IPM

DHCPv6 with IPv6.
DHCPv6 relay As it turns out, #DHCPv6 relaying works a bit differently to relaying in IPv4 DHCP as the client messages are encapsulated unmodified by the DHCPv6 relay. The long awaited post about relaying DHCPv6 is finally here:

Performance tips! * Think more about how much resources your page have to download to the client * Round trip latency, DNS resolve, TCP e SSL Handshake, matter! * After all don't forget to the server response time. * Others detail can make the difference too, how: "TCP congestion window" and "SSL OCSP". Bonus Performance can make huge impact in work business, think about #webperf #perfmatters (Print of the book "The Performance of Open Source Applications")

Nothing major for you on #day9 of the #cybertechdave100daysofcyberchallenge. I solved three labs related to scanning networks. One lab is still left, intentionally for later. Here are a few points that I discovered in labs ( new to me, might be the same for you ) : 1️⃣ DNS doesn't just run on UDP but can also run using TCP. This is the first time I came across it (screenshot attached below). 2️⃣I found out about a protocol ( new to me ) - TFTP ( Trivial File Transfer Protocol ). You would have heard about FTP and the SFTP ( Secure version of FTP ) but have you heard about TFTP? Here's a bit that I dug about it: TFTP is typically not used by any of us but by network devices like routers, switches, etc. They do so to exchange files related to configurations or so. Unlike FTP and SFTP ( that runs on TCP ), TFTP runs on UDP, so file transfers are connection-less. Also, TFTP operates in local networks ( LAN ) only and doesn't communicate or transfer to the internet. That's it. See you on the 10th day. #networking #nmap #penetrationtesting

How to reset network settings? Today we will show you how to perform a quick manual network reset. First, we need to run the command prompt as an administrator. Then enter the following commands in turn: 1. netsh int ip reset 2. ipconfig /release 3. ipconfig /renew After executing these commands, you only need to restart the PC . #redfishiaven #Network #settings #reset

DNS is moving towards static stability, where serving a slightly outdated IP address is better than serving none at all. Since DNS can be a single point of failure, choosing the right TTL (Time to Live) for records is crucial. A shorter TTL ensures quicker updates but increases DNS query load, while a longer TTL reduces queries but might delay updates. Finding the balance ensures reliable and responsive DNS service. #DNS #InternetInfrastructure #StaticStability #TTL

♦️What is DHCP ? (Dynamic Host Configuration Protocol) is a network management protocol used to dynamically assign an IP address to any device in network .DHCP assigns new IP addresses in each location when devices are moved from place to place, which means network administrators do not have to manually configure each device with a valid IP address or reconfigure the device with a new IP address if it moves to a new location on the network. ♦️How DHCP works DHCP runs at the application layer of the TCP/IP stack. It dynamically assigns IP addresses to DHCP clients and allocates TCP/IP configuration information to DHCP clients. This information includes subnet mask information, default gateway IP addresses and domain name system (DNS) addresses.
