In summary there is an on-premise DNS zone(e.g. example.com) and a Route53 private hosted zone(e.g. cloud.example.com). The goal is to run a custom DNS service using Bind DNS in AWS. Using DHCP options to point all EC2 instances to use the custom DNS services and have forwarders from inside to these custom DNS services.

EDNS Client-Subnet (ECS) is an extension to the DNS protocol to include components of the end-user IP address data in requests that are sent to the authoritative DNS servers. This means that there is a privacy “leakage” for recursive resolvers that send ECS data, where components of the end user’s IP address are transmitted to the remote

Unfortunately ECS does not support registering services into public DNS namespaces. In his article Update IP-Address in Route53 on ECS Fargate redeployments Marc Logemann came up with an approach You can also use namebench to benchmark different DNS servers . For example: $ namebench 1.1.1.1 8.8.8.8 9.9.9.9 -x -O. You want your DNS resolver to be as close to you as possible, especially if your DNS server does not support EDNS Client Subnet (ECS).

Because of that, AWS makes it easy to create a load balancer or add your service to an existing target group when you're setting up a service. Rena ip-adresser är svåra att komma ihåg, och därför använder man sig av dns-servrar. När du skriver in www.sweclockers.com i adressfältet i din webbläsare skickas en förfrågan till din dns-server om vilket ip sweclockers har. dns-servern i sin tur kommunicerar med andra dns-servrar och kan tillslut ge dig svaret 217.75.102.137. EDNS-Client-Subnet (ECS) is a draft informational RFC that uses the EDNS0 extensions to the DNS. Recursive DNS services that support ECS can provide the client (end-user) subnet as part of the DNS query, allowing authoritative DNS providers to use this extra information to make more informed traffic routing decisions.

DNS server—this network service provides and supports DNS operation. The DNS server may be responsible for the specific zone in which the corresponding computers are located. Since the DNS system is hierarchical system, the DNS server can redirect the request to the upstream server if it cannot determine the IP address of the host by the domain name.

We want each container to be always accessible on the same public Although it's not free, normally if you want a public DNS name to an ECS service (fargate or EC2) you'd front it with a load balancer (which can also do SSL termination, if you so desire). Because of that, AWS makes it easy to create a load balancer or add your service to an existing target group when you're setting up a service. Rena ip-adresser är svåra att komma ihåg, och därför använder man sig av dns-servrar.

ECS is a DNS extension proposed in 2011 by a group of DNS and CDN operators. When sending DNS queries to authoritative DNS servers (like NS1's), ECS-enabled DNS resolvers may send a portion of the IP address of the end user.

fetch your containers' public IP after redeployment and ; upsert your public Route 53 record set with that IP. ECS is highly reliant on working DNS. DU (Data Unavailable) can be caused if DNS resolution is not working. Every change on DNS config need to be confirmed with the customer before making any changes. EDNS Client Subnet (ECS) is a mechanism for the desired source IP address of a DNS query to be embedded within the EDNS information of a DNS packet. The authoritative DNS server supporting ECS will read this source information and answer with the A record of the best located server possible. Good. The parent server a.nsset.be has your nameservers listed. This is a must if you want to be found as anyone that does not know your DNS servers will first ask the parent nameservers.
