You’re forgetting in the explanation that a domain can have multiple A records so if one server of the IP pool is down, the traffic will go to the second A record. And in some cases, banks use www# instance, it’s because of the service type for not mixing systems, for example www2 is for personal banking system, www3 is for enterprise banking system and so on.

@@DeadlyDragon_ GSLB is not just for "very large global environments". It's used any time you want to load balance without the traffic going through the load balancer. It's absolutely required for some things that cannot be proxied or NAT'ed easily, traffic that is destined for different datacenters, or load balancing of things based on other types of records (e.g. MX records mapping to a series of mail servers). GSLB is just "DNS with smarts". There are cases where you might use GSLB even if you're not load balancing, and you just want the DNS response to be subject to health checks/server availability.

1) a CNAME record on the higher level domain is more than possible, however it will redirect everything including mail exchangers and such to the CNAME. 2) a lot of WWW1 and WWW2 are to get around 302 redirect caching on larger older sites too.

Your example of the Wolfram Alpha subdomain is used for tracking how many people incorrectly type their domain name. There will be some tracking code logging which domain the redirect came from or they may simply use it as an identifier when they are checking their server logs.

www1 is often used for different versions of a website. e.g. if a new version of the website has not yet been fully translated and you call up a language that is not translated you will be redirected to an old version of the website at www1 where the language was translated.

Some load-balancers support "sticky sessions" and always redirect the same user/context to the same server. Perhaps www1,2,3 is an old-school easier way to make sure each subsequent request stays on the same server.

@mihiguy

Жыл бұрын

not necessarily oldschool, when your website/webapp is hosted at multiple sites and you try to route your session to the fastest server - DNS does not in general do this well if you need sticky sessions even if the user changes network (e.g. wifi to mobile) which may change location-based DNS results. You can work around this on the server, but why do you need to hide it? If you use sticky sessions, the session ID will in any case have some "worker ID" embedded, so technical people can always find out whether their session is on the same server or not.

I'm a sysadmin and we are using different subdomains to connect to different servers for different use cases. The customer can instantly see from the domain and the top domain, that this side is valid and from us, while we can keep the servers separated. It's really useful and easy

Few things that are a little wonky in this: • The misspelt domain is an ad domain so not really owned by the true company. • A records can be used to load balanced, either by having multiple entries, changing responses (using something like AWS’ Route5) and an IP can go to multiple servers/data centres. This is how services like Cloudflare DNS and Google DNS (shown as example IPs in the video) work. Any cast IP systems allow for this hence how you can always use 1.1.1.1 for CF, though they are not a default option a lot of the time and tend to be used by large enterprises/infrastructure systems.

Naked domains can have more than A records; they can also use CNAME to dynamically point to another address, and that's typically used with addon domains for a main domain, or they can use AAAA records to point to an IPv6 address.

@LeifNelandDk

No, naked domains can't have CNAME records, unless it's internal in the server itself, so the nameserver looks up the ip of the CNAME and return to client asking for it.

Bruh, this isnt even about the video

A reliably 'ThioJoe' video, this. Good work. Another seemingly niche fact that we all glaze over, without even knowing that it's worthy of examination.

It’s not actually the beginning of every website and it’s not necessarily browsers hiding it. It’s a completely optional subdomain that *was* a common convention but nowadays is mostly only used so that people who stubbornly type it in don’t receive an error page. And it’s not the browser doing the redirect, it’s the server. The load balancing can also happen at the IP level (the actual server exposed through an IP address can change).

HP's UK site frequently switches to www8. I'd always wondered why. I even worried at first that it was a fake sure.

People use www1 or www2 etc. for load balancing domains with large user loads. Each one is a different server.

When I clicked on this I thought it was going to be clickbait. But the tech dns stuff and the short history was worth the click. Thanks.

A bit of clarity, backup and load balancing are different practises, load balancing a group of servers share the work through some rerouting, and backup servers pick up the load when a primary server is unavailable. I suspect backup servers are less frequent now on large systems, load balancing sorting out fail over. But a large project may not want to roll out updates to all their servers at once, exposing them to loss of service if there are any problems.

I'd rather use interface on correct domain name, than on typo'ed one. If this would be some banking page or email, I would be pretty scared, because I should already passed some credentials over the server. Nevertheless, people should be carefull what they type in their browsers, because not every Facebook misstyped domain is exact Facebook interface. They are used for phising attacks. Stay safe!
