¿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.











this topic to be actually something which I think I would never understand.
It seems too complex and very broad for me. I am looking forward for
your next post, I will try to get the hang of it!
that I can be myself more than wherever else in everyday living and that I get

Understanding the processes and protocols within a Professional Tenure Committee (PTC) is crucial for faculty members. This Frequently Asked Questions (FAQ) guide aims to address common queries related to PTC procedures, voting, and membership.
1. Why should members of the PTC fill out vote justification forms explaining their votes?
Vote justification forms provide transparency in decision-making. Members articulate their reasoning, fostering a culture of openness and ensuring that decisions are well-founded and understood by the academic community.
2. How can absentee ballots be cast?
To accommodate absentee voting, PTCs may implement secure electronic methods or designated proxy voters. This ensures that faculty members who cannot physically attend meetings can still contribute to decision-making processes.
3. How will additional members of PTCs be elected in departments with fewer than four tenured faculty members?
In smaller departments, creative solutions like rotating roles or involving faculty from related disciplines can be explored. Flexibility in election procedures ensures representation even in departments with fewer tenured faculty members.
4. Can a faculty member on OCSA or FML serve on a PTC?
Faculty members involved in other committees like the Organization of Committee on Student Affairs (OCSA) or Family and Medical Leave (FML) can serve on a PTC, but potential conflicts of interest should be carefully considered and managed.
5. Can an abstention vote be cast at a PTC meeting?
Yes, PTC members have the option to abstain from voting if they feel unable to take a stance on a particular matter. This allows for ethical decision-making and prevents uninformed voting.
6. What constitutes a positive or negative vote in PTCs?
A positive vote typically indicates approval or agreement, while a negative vote signifies disapproval or disagreement. Clear definitions and guidelines within each PTC help members interpret and cast their votes accurately.
7. What constitutes a quorum in a PTC?
A quorum, the minimum number of members required for a valid meeting, is essential for decision-making. Specific rules about quorum size are usually outlined in the PTC's governing documents.
