Whenever a domain is switched between registrars or change an IP address, you are more likely to face delays caused by the DNS propagation. This can hardly be avoided, but its impact can be reduced to some extent.

The domain name server propagation is basically the time taken to update the DNS records across the DNS infrastructure around the globe. The DNS system basically helps in keeping the load on your nameservers low due to the caching feature it holds. It is due to the caching mechanism that gives rise to the DNS propagation, if it wouldn’t have been there, all the requests made to your domain would have flooded your nameservers for every lookup, which would have inturn put more pressure causing to malfunctioning or even non-functionality of these servers.

There are resolvers, a kind of servers that takes care of running the DNS queries for the web users, cache a copy of the zone files of any domain at the very beginning when a request is made for an information about a domain. Until the next cache update, all the DNS queries are served from the most recent zonefile that cached in the system. Such a mechanism helps in reducing the overall process load and bandwidth of a DNS nameserver.

The main reason for the propagation is basically the DNS caching. Consider a situation where a resolver has cached a zonefile for approximately 5 hours and the IP address has been switched to a different one and the records have been updated in the nameserver after sometime within this while, then the resolver would still exhibit the incorrect DNS information for approximately 5 minus the time at which the IP was changed. Only after all the resolvers from all across the globe are updated with the latest zone file, we say that the propagation has been completed.

At-times the DNS Cache gets poisoned or polluted, check more on this here – DNS Cache Poisoning

This was about the general procedure, but being an owner of a domain, you can set time within the zonefile called as the Time To Live (TTL). In there you must assign time in seconds which tells the DNS resolver about the applicable cache for a zonefile before it comes back asking for a new one. As a default value 14400 seconds ie. 4 hours are set. Though domain owners may make changes to these DNS settings, you must keep in mind that the changes would take effect in approximately 24 hours. Ofcourse, you must also check with your ISP whether they allow the TTL settings to be changed.

Not many are aware about the multiple uncontrollable factors that affect the DNS propagation time for a particular domain name. It may take anywhere between a couple of hours to approximately 48 hours for the propagation to complete.

What are the factors that affect the DNS propagation time?

TTL (Time to Live) Settings — As discussed above the TTL is set for every domain name server record which is help within the zone file. It is the period of time for which the servers cache the information for DNS records. Lesser the time set, causes to an increase in the number of queries to your nameserver, causing an increase in load resulting in a degraded server performance.

ISP (Internet Service Provider) — The ISP would usually cache the DNS records at their end inorder to avoid retrieving retrieving information from your domain name server everytime. This also helps them serve the requests faster hence increasing the surfing experience for users. Few ISP’s maybe an exception to this by overlooking the TTL settings and only update their cached records after fixed intervals of time.

Domain Name Registry — If the DNS’s are changed, the changes are forwarded to the registry after-which the new record updates is processed to the root zone. Different registries might take different times to update the records as their TTL setting are set high for the name server records. Moreover, even though recursive nameservers doesn’t cache the root NS records usually, though few ISPs cache the information anyway, further resulting in a delay in the propagation time.

Regardless of the Industry or niche, getting yourself an appropriate domain name plays a vital importance for any business entrepreneur. It is your identity over the world wide web and a brand that would be referred by your customers and users. But, if you try to find an excellent domain name suitable for your business, you would realize that most of those domains have already been registered. Though there still are some that are readily available and using appropriate techniques one should easily be able to find valuable domain names relatively easily. There are number of newbie webmasters who register domain names for wrong reasons.

In this article we have tried to explain you the ways to determine if a domain name is actually valuable.

Keywords and SEO Attributes for Domain Names

An ideal method of finding a domain-name that has a greater value is to find out names containing the keywords that are searched more often. Such domains hold the capability of generating potential traffic almost instantly, moreover there are minimal efforts that needs to be taken on such domains. Domain names containing the keywords are referred to as an ‘exact match domains’, and are the most desirable ones among the list. Such domains offers an ability to webmasters to instantly capitalize on organic search engine traffic, without the need for carrying out every usual SEO activity. You may also manage to find few domains that have expired recently but still hold various SEO attributes such as backlinks and PageRank. Buying such recently expired domain names can be a good way of finding valuable domains.

Aspect of Commerciality and Profitability in Finding Domain Names

An important aspect when looking for domain name is its aspect of commerciality. Even if you are able to find an exact match domain, it should be something that holds a good commercial value. Most would agree that, there are certain keywords that are more likely to be searched when an individual is looking to purchase a product or service, whereas some other keywords are often searched with a purpose of simply getting some information. Lets consider an example, a domain name “whatisadomain.com” holds a much lesser commercial value that “howtoregisterdomainname.com”, here the second domain is more likely a keyword which is being searched by an individual who probably wishes to register a domain name hence has a better chance of conversion.

Relevance

Not to mention that, a domain name must be such that it can be remembered easily and is relevant to the theme of the website. This would not only help visitors to remember it, but can be easily shared among individuals, hence enabling returning visitors and gaining popularity easily. Alternatively, one may use an exact match domain name which broadly covers the niche, with this you get a scope to use multiple keywords within the content of your site which is relevant to the products or services you offer. This would enable you to concentrate on a broader spectrum of niche keywords and attract an increasingly larger volume of traffic over the web in the long-term.

DNS is an abbreviated term used for Domain Name System, it is the largest database across the world which holds the registration information about every active domain name over the world wide web. Many webmasters also refer a DNS server as Name Server. The information present within the domain name system includes but isn’t limited to the information related to the web host, the domain registrant, and the active name servers for the domain. Every web hosting uk provider offers a minimum of two name servers, it enables the website to send and receive information to-and-from the web.

The concept behind Name Servers

Thousands of DNS servers are situated at nations across the globe. They all hold some portion of database of the domain name system. For maintaining redundancy and security of this database there are thirteen root DNS servers that hold the complete information of the database on every server.
Two main types of DNS servers primary exist, namely the Primary DNS servers and the Secondary DNS servers. Though any web server can be used as a DNS server similarly any DNS server can be used as a primary or secondary server. The server administrator can opt between the choices of using a server as primary or secondary server. Moreover, it is also allowed to use a single server as a primary server in a zone and as a secondary server in another zone.

What Are Primary DNS Servers?

The primary DNS server carries out the responsibility of  reading the information regarding a domain zone from a file which is stored on the web server of a hosting package. It is the responsibility of the primary server to communicate with the secondary DNS server, and this process is called the zone transfer due to the basic fact that the zone data is exchanged between DNS servers. Every domain-name is assigned to the DNS servers for the purpose of achieving redundancy and for simplifying the process of server administration. Incase the primary server holds the zone data about a particular domain name, then that data isn’t required to be replicated as the primary and secondary server share zone data on a continuous basis between each other. In simple terms, when a request is made to the server it passes via. primary DNS server which then allocates functions to the secondary DNS server.

What Are Secondary DNS Servers?

The secondary DNS server is referred as the Slave server. It carries out the task of taking data from the primary DNS server instantly as it is set-up.
A minimum of two authoritative name servers are essential for every DNS domain, so at least one secondary nameserver should be configured. The secondary or slave DNS download or copies information for the domain from the primary server and provides answers to the queries about that domain periodically. A certain time frame is set on how long the secondary nameserver can continue answering the queries when it cannot contact the primary. Despite the fact that a secondary nameserver automatically copies its information from the primary, the DNS does not differentiate between primary and secondary nameservers.  More-or-less, they are used equally whenever a domain name lookup is performed. These Secondary servers are equally necessary as the primary DNS servers. Mitigation of the load over the primary DNS server is handled by the Secondary servers as well.
