1/10: 🌐 Welcome to Networking Basics 101!

Let's start with IP addresses. 📡

An IP (Internet Protocol) address is a unique numerical identifier assigned to devices on a network. It's like a phone number for your device on the internet. #NetworkingBasics Image
2/10: 🔢 IP addresses are divided into two main versions: IPv4 and IPv6.

IPv4 uses a 32-bit address format (e.g.,,
while IPv6 uses a 128-bit address format
(e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). #IPv4 #IPv6 PS: https://www.wpdownloadm...

¿Conoces la técnica de #Phising?, o como se pueden interceptar paquetes entre la comunicación de dos equipos, o incluso engañar a un Switch con su tabla de #ARP. Este tipo de técnicas se pueden realizar usando DSNIFF.
Te enseño a montar un escenario de pruebas sencillo Abro🧵👇
Lo primero. ¿Que es DSNIFF?
Es un conjunto de herramientas creadas para auditar redes y realizar tests de penetración creadas por Dug Song
Con esta herramienta te das cuenta de lo importante que puede llegar a ser la #encriptación en comunicación
Aunque la Suite tiene un conjunto de herramientas amplio, en este estudio únicamente nos vamos a centrar en 2 de ellas.

TECH Thread 🧵 Web3 Domain Name Collision


🙋‍♀️ Can someone else own the same name?
🙋 Which name will be the one that works?
🙋‍♂️ Who are @HNS, @decentra_web, @freenameio, @ensdomains, @unstoppableweb

🧵⬇️ Like, Share & RT Plz🧵⬇️
❓What is a Name Collision ❓

In #Web2 a collision occurs when an attempt to resolve a #domain name in a private namespace results in a query to the public #DNS

When private and public domain namespaces overlap, it can create security risks, confusion, and systems failure.
While traditional #Web2 domain names are organized by @ICANN , there is no such governing body or alliance in #Web3.

In Web3, “domains” are used to send and receive #cryptocurrency in place of lengthy alphanumeric wallet addresses and are a vital component of Digital #Identity

10-21-22: Internet Framentation Panel Discussion
- James Bladel (VP of policy @GoDaddy) stated
"I would propose that we would turn the multi-stakeholder model inside out. Normally I think we're familiar with everyone coming from government/industry/technology/academia..."
"...and bringing our perspective into ICANN to advance the work but I think that has to flow the other direction as well and we have to be comfortable taking our knowledge/expertise & our appreciation for the multi-stakeholder model back to our day jobs..."
"...whether that's in government or industry and recognizing when maybe an attempting piece of legislation - or a new protocol - undermines the interoperability of the internet..."

TECH Thread 🧵 DNS Root Zone & Alt Roots

❓What is a #DNS Root Zone❓

The “Root Zone” is the highest level of the Domain Name System structure. It contains the names and the numeric IP addresses for all top level #domain names such as .com, .net & .org

👇 Continued 👇
❓How does the Root Zone work❓

Every time you try to connect to a website or any other online service, and enter a web address your their browser, this action triggers a DNS lookup, and all DNS lookups start at the root zone.
Once the lookup hits the root zone, the lookup will then travel down the hierarchy of the #DNS system, first hitting the TLDs servers, then the servers for specific domains (and possibly #subdomains)

Hardly anyone has heard of Sophia Yuferev - a disabled woman, whose body was found in her flat months after all her benefits had been removed.

She'd been hounded for years by the DWP, & repeatedly failed by other public bodies.… via @johnpringdns
Sophia was a talented artist who lived with significant mental distress, & had been living on a sandwich a day for the last few months of her life after both her employment & support allowance (ESA) & her personal independence payment (PIP) had been stopped.
Her body was discovered by police in her flat in Hornchurch, Essex, in November last year, weeks after she had died.

Her electricity had been cut off months earlier for non-payment of bills.

People willing to start up are often worried about the initial set-up costs and it is a valid reason to worry about.
But when you dig a bit deeper you realise that with the ecosystem today you can create and run a startup in the most frugal yet effective way possible. 🧵
I have highlighted tools and ways to run your startup for free. This is decent enough to handle about ~ 500K requests easily, but of course it's application dependent too. Please feel free to suggest any other awesome resources I might have missed. #startup
@discord Use discord for #communication, discord can be configured to work like slack. Best part, discord is completely free, while slack averagely charges $10/user/month.

Here are some of the big reasons #ensdomains have been getting so much attention!

For those who are wondering:

1a. - DNS

To really understand #ensdomain you first need to know their web2 counterpart: #dns, which means "domain name system". We take for granted what it does for us because we don't have to remember numbers like "" in order to get to

But, without DNS, we would have to (sort of; there were other protocols developed as solutions before DNS, but DNS is what we have been using since 1983. The previous solutions were not very efficient, but I won't go into a tangent about them).

What is Domain Name System (DNS)? | How DNS works?
DNS lets users connect to websites using domain names instead of IP addresses. Learn how DNS works.

A Thread 🧵 👇🏻

#DNS #Thread #CloudComputing #cloud #Security Image
DNS stands for Domain Name System.

DNS is the system that translates domain names into IP addresses, allowing your network to find the correct website and your browser to load it. Here is a breakdown of the five DNS steps involved in loading a webpage. 👇🏼
1️⃣ DNS Cache

When you search for a website, it will be stored on your system's DNS cache and retrieved from there if you have visited it before.

If cached, the rest of the DNS search ends here.

Hoy voy a hacer un pequeño hilo sobre: "Como borrar la caché DNS en Windows 10/11"

🤨- "¿Pero qué me estás contando fantasma? Haces un ipconfig /flushdns y andando. ¡Anda que hacer un hilo para esto!"

Vale si... ¡PERO NO! ¡Acompáñame en este viaje por la caché DNS de Windows! Image
En primer lugar, un inciso:

Cache DNS de tu ISP o proveedor DNS ➡️ Cache DNS de tu Router ➡️ Cache DNS de Windows ➡️ Cache DNS del navegador

¿A que mola el chorro de lugares donde puede almacenarse un registro DNS? ¿Vas pillando ahora el tema no? ¡Pues seguimos!
De todo ese chorro de cachés puedes controlar fácil la del router simplemente accediendo y borrándola (en Mikrotik por ejemplo IP->DNS->Cache->Flush Cache) o bien a lo bestia reiniciando el cacharro y punto...

Journée #Josy sur le #DNS

Premier à parler, @remasse (@AFNIC ) qui va exposer les grands principes.
Résolution #DNS (« ça doit marcher 100 % du temps ») puis cycle de vie du nom de domaine (pensez au renouvellement) pour lequel, dans un .fr, on doit passer par un BE (Bureau d'Enregistrement).

L'évolution du .fr : très petit jusqu'en 2004 car enregistrement très restrictif (« nous avions fini par prendre un .com »)

Depuis les réformes de 2004 et 2006, .fr décolle. Bientôt 4 millions de noms.

In light of the recent #SupplyChain attack on @KaseyaCorp by #REvil, it is worth paying attention to decoder[.]re included within the ransom notes, used additionally to 'mirror' in TOR network. #Ransomware #Cybersecurity #ThreatIntel #ThreatHunting #Malware Image
Similar to decryptor[.]cc and decryptor[.]top in previous #REvil/#Sodinokibi versions, decoder[.]re is used to grant the victims access to the threat actors WEB-site for further negotiations should their connection be limited via #TOR. Image
To access the page in WWW or TOR - the victim needs to provide a valid UID (e.g. "9343467A488841AC") ImageImage

Une récente annonce gouvernementale sur la censure de l'Internet a entrainé le flot habituel de tweets « ah, ah, quels incompétents au gouvernement, ils n'y connaissent vraiment rien. » #DoH 1/5
Ces réactions relèvent de deux erreurs : d'abord, croire que l'adversaire est bête. C'est parfois vrai, mais c'est souvent dangereux de s'illusionner ainsi. 2/5
Si des gouvernements prennent de mauvaises décisions, ce n'est pas de l'incompétence, c'est un choix politique délibéré.… @laquadrature 3/6
