1
The Domain Name System, or DNS, is like the phonebook of the internet.
2
It maps human-readable URLs or hostnames like www.fireship.io to the IP address of the server that hosts that site.
3
When you type a URL into the browser, it makes a DNS query to figure out which unique IP address is associated with that hostname.
4
First, it'll attempt to look in the local browser or operating system cache, But if the cache is empty, then we need to look up the IP address in the phonebook,
5
which is the job of a server known as the DNS recursive resolver.
6
It's recursive because it needs to make multiple requests to other servers, starting with the root name server,
7
which itself will respond with the address of a top-level domain DNS server, which stores data about top-level domains like .com or .io.
8
The resolver makes a request there, which will respond with the IP address of the authoritative name server.
9
That's the final source of truth that contains the requested website's IP address.
10
That gets sent back down to the client and is cached for future use.
11
That sounds complicated, but it all happens within a fraction of a second.
12
You can think of it as a globally distributed database that handles more requests than any other database in the world.
13
When you register a domain name, it's handled by a registrar accredited by the nonprofit organization ICANN.
14
The record is then maintained by a registry operator, who stores your DNS settings and propagates them to other DNS servers around the world.
15
As the registrant, you'll be assigned a zone file where you can configure the settings of your domain.
16
Every zone has a Start of Authority record to tell other DNS servers who's in charge of that domain.
17
But most importantly, we have the A record.
18
It means address and maps a domain or subdomain to the IP address of its host.
19
In other cases though, we may want to forward a domain to another domain on the internet instead of an IP address.
20
In which case, a canonical name or CNAME record would be used.
21
We have MX records for email, and we can store arbitrary data with text records, which is often used to communicate with third parties to verify ownership of the domain.
22
And finally, we have the NS, or Name Server record, a URL that the internet can ping to find our IP address, and there's almost always two of them for better reliability.

Woordenschat en spreektips bij deze les
Deze spreekles op niveau C1 is gebaseerd op de video “DNS Explained in 100 Seconds”. Deze woorden komen het vaakst terug: domain, address, server, Dns, record. Deze video bevat 25 zinnen en 459 woorden om na te spreken. Het gesproken deel duurt 2:15. De spreker praat snel, ongeveer 204 woorden per minuut, dus reken op verbonden en ingeslikte klanken. Slechts 74% van de woorden hoort bij de 3.000 meest gebruikte Engelse woorden, dus de woordenschat is pittig.

| configure werkwoord | /kənˈfɪɡə(ɹ)/ | configureren |
| propagate werkwoord | /ˈpɹɒpəˌɡeɪt/ | propageren |

Grammatica in deze video
De structuren die de spreker het meest gebruikt, met de exacte woorden uit de video:
| Structuur | In de video |
|---|---|
| Lijdende vorm be + voltooid deelwoord — het gaat om wat er gebeurt, niet om wie het doet | is associated · is cached · be assigned |
| Betrekkelijke bijzinnen who / which + zin — extra informatie over een persoon of ding | there, which will · records, which is |
Uitspraak om op te letten
- De klanken “sh” en “zh”: cache /kæʃ/, fraction /ˈfɹæk.ʃən/
- Lange woorden — let op de klemtoon: authoritative /əˈθɔɹɪˌteɪtɪv/, canonical /kəˈnɒn.ɪ.kəl/, arbitrary /ˈɑː.bɪ.tɹə.ɹi/, importantly /ɪmˈpɔɹ.tənt.li/
Klanken die Nederlandstaligen lastig vinden:
- Stemhebbende eindmedeklinker — /b/, /d/, /g/, /z/, /v/ niet verscherpen: recursive /ɹɪˈkɜː(ɹ)sɪv/, authoritative /əˈθɔɹɪˌteɪtɪv/
- /æ/ — opener dan de Nederlandse “e”: cache /kæʃ/, fraction /ˈfɹæk.ʃən/
- /g/ — een harde plofklank, geen Nederlandse “g”: configure /kənˈfɪɡə(ɹ)/, propagate /ˈpɹɒpəˌɡeɪt/, globally /ˈɡloʊbəli/
Zo oefen je met deze video
- Luister de hele video één keer zonder te spreken en noteer de woorden die je niet kent.
- Begin op 0,75× snelheid, spreek zin voor zin na en ga terug naar normale snelheid zodra het makkelijk gaat.
- Neem jezelf op en vergelijk met het origineel; let daarbij op woorden als cache, recursive, configure.
Wat is de Shadowing-techniek?
Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
