¿Que es el DNS Flag Day?
El día en el que veremos internet arder (el apocalipsis)….
El 01 de febrero de 2019 cuatro de los principales proveedores de DNS Resolver, realizarán un lanzamiento de su software con una característica en común; la cual, es que se manejará el estándar EDNS de forma estricta. Esto presenta el fin de parches temporales históricos que perdonaban ciertas conductas desviadas del estándar en los servidores DNS autoritativos.
Dentro de los problemas que se tienen se encuentran:
- DNS autoritativos que bloquean respuestas.
- Malas implementaciones de DNS que no siguen los estándares.
- Protecciones de seguridad (Firewalls, IDS/IPS, etc) mal implementados o con malas practicas que bloquean el trafico que sigue el estándar.
- Los Resolver deben esperar timeout y reintentar con TCP y sin EDNS.
Por estos días algunos DNS públicos (Google, Facebook, PowerDNS, CloudFlare, Quad9, Cisco, etc) también realizaran estos cambios.
¿Qué es EDNS RFC 6891?
Define un mecanismo compatible con DNS para indicar soporte para nuevas opciones incluyendo soporte para paquetes más grandes (sobre 512 bytes), más códigos de respuesta, etc.
¿Para qué sirve EDNS?
Es requerido para para que funcionen las siguientes extensiones:
- NSID -- RFC 5001: identificación de instancia del servidor
- DNSSEC -- bit DO: por favor, responda con registros DNSSEC
- Client-subnet, RFC 7871: desde qué red viene esta consulta?
- Keep-alive, RFC 7828: timeout variable para DNS sobre TCP.
- Cookies, RFC 7873: mecanismo liviano de seguridad.
- Las nuevas extensiones y funcionalidades que en el futuro se puedan adicionar...
¿Qué impacto tiene este cambio sobre el modulo GTM/DNS de F5?
Dado que el servicio de GTM/DNS de F5 es un servicio de DNS y una de sus implementaciones es responder de forma autoritativa, éste debe seguir el estándar DNS y cumplir de forma estricta los RFC’s que definen el servicio.
Por esto se hace necesario realizar una validación de los servicios que pasan por F5 GTM/DNS con el fin de prevenir una posible afectación del servicio.

**娛樂城與線上賭場：現代娛樂的轉型與未來**
在當今數位化的時代，"娛樂城"和"線上賭場"已成為現代娛樂和休閒生活的重要組成部分。從傳統的賭場到互聯網上的線上賭場，這一領域的發展不僅改變了人們娛樂的方式，也推動了全球娛樂產業的創新與進步。
**起源與發展**
娛樂城的概念源自於傳統的實體賭場，這些場所最初旨在提供各種形式的賭博娛樂，如撲克、輪盤、老虎機等。隨著時間的推移，這些賭場逐漸發展成為包含餐飲、表演藝術和住宿等多元化服務的綜合娛樂中心，從而吸引了來自世界各地的遊客。
隨著互聯網技術的飛速發展，線上賭場應運而生。這種新型態的賭博平台讓使用者可以在家中或任何有互聯網連接的地方，享受賭博遊戲的樂趣。線上賭場的出現不僅為賭博愛好者提供了更多便利與選擇，也大大擴展了賭博產業的市場範圍。
**特點與魅力**
娛樂城和線上賭場的主要魅力在於它們能提供多樣化的娛樂選項和高度的可訪問性。無論是實體的娛樂城還是虛擬的線上賭場，它們都致力於創造一個充滿樂趣和刺激的環境，讓人們可以從日常生活的壓力中短暫逃脫。
此外，線上賭場通過提供豐富的遊戲選擇、吸引人的獎金方案以及便捷的支付系統，成功地吸引了全球範圍內的用戶。這些平台通常具有高度的互動性和社交性，使玩家不僅能享受遊戲本身，還能與來自世界各地的其他玩家交流。
**未來趨勢**
隨著技術的不斷進步和用戶需求的不斷演變，娛樂城和線上賭場的未來發展呈現出多元化的趨勢。一方面，虛
擬現實（VR）和擴增現實（AR）技術的應用，有望為線上賭場帶來更加沉浸式和互動式的遊戲體驗。另一方面，對於實體娛樂城而言，將更多地注重提供綜合性的休閒體驗，結合賭博、娛樂、休閒和旅遊等多個方面，以滿足不同客群的需求。
此外，隨著對負責任賭博的認識加深，未來娛樂城和線上賭場在提供娛樂的同時，也將更加注重促進健康的賭博行為和保護用戶的安全。
總之，娛樂城和線上賭場作為現代娛樂生活的一部分，隨著社會的發展和技術的進步，將繼續演化和創新，為人們提供更多的樂趣和便利。這一領域的未來發展無疑充滿了無限的可能性和機遇。

Samsung's Galaxy Tab four 10.1 would not fare well here. Our concern here
is that not like HTC's Sense UI, there's no means to change
the fast jumps to anything that matches your fancy; you're caught with this trio.
They're right here to ensure you may capture a whiteboard or say
hiya on Skype, and not much else. Falco peregrinus peregrinus, the nominate (first-named) subspecies, described by Tunstall in 1771, breeds over a lot of temperate
Eurasia between the tundra in the north and the Pyrenees, Mediterranean area and Alpide belt within the south.
The fossil report of the genus Cygnus is sort of impressive,
although allocation to the subgenera is commonly tentative; as indicated above, at
the very least the early types most likely belong to the
C. olor - Southern Hemisphere lineage, whereas the Pleistocene taxa
from North America could be positioned in Olor. Give the
Transformer Pad an in depth look if you are at the very least mildly curious in regards to the dock; just ensure to maintain its competitors in mind

to argue that there is not any real competition for the TF103C,
