Advantages and disadvantages of Dynamic Routing
« on: October 11, 2013, 08:28:40 AM »
Advantages of Dynamic Routing

• Simpler to configure on larger networks
• Will dynamically choose a different (or better) route if a link goes down
• Ability to load balance between multiple links

Disadvantages of Dynamic Routing

• Updates are shared between routers, thus consuming bandwidth
• Routing protocols put additional load on router CPU/RAM
• The choice of the “best route” is in the hands of the routing protocol, and not the network administrator

Dynamic Routing means that the location of the remote resource is decided at run time. The decision is taken by a CICS®-supplied user-replaceable routing program. The routing program may, at different times, route requests for a particular resource to different regions. This means, for example, that if you have several cloned application-owning regions, your routing program could balance the workload across the regions dynamically.

Static advantages - deterministic, no bandwidth use by dynamic RP.
disadvantages - does not scale well, admin overhead, does not respond to faults without manual intervention.

Dynamic Advantages:
Scales better. Depending upon choice of protocol up to a planetary scale. Automatically re-routes around link failures
disadvantages: uses bandwidth, less control over selected traffic paths.

    Certain services that have a sensitivity to which IP you use, such as authenticated services on web servers and file downloads, might not run well if your connection fails on a dynamic IP. With a static IP, a small interruption in your connection might not terminate your packet exchange with the service, making the connection virtually seamless. Such services usually base themselves on the TCP protocol.


    Since you don't have to change your IP address, you don't have to rely on a DHCP server, either. If you had a dynamic IP and then your DHCP server -- the server from your service provider that gives your computer an assigned address -- would have issues, you wouldn't be able to renew your address when necessary, which would probably terminate your connection to the Internet temporarily. Your static IP would be configured into your network interface, so you wouldn't have to request an address.


    If you plan to host a game server, you'd have the least amount of trouble hosting it under a static address. Without such an address, you must inform the clients whenever your IP changed.

Remote Access

    If you connect to your computer from a remote location, you don't have to worry about the IP changing while you're connected to it. You also don't have to worry about losing the IP when you connect through an application such as Remote Desktop.

Reduced Down Time

    Your IP never resets, meaning that your computer doesn't have to send any requests for renewal. If you send a request for an address renewal, your Internet might go down in the process, interrupting something that you might have been doing at the time. If you run a business, going with a static IP becomes a wise choice for seamless connectivity.


    Static IPs only use a single, exact address. In effect, static IDs are more prone to hacking attempts than dynamic IPs. Moreover, you cannot easily change a static IP once it has been hacked -- making your system extremely prone to continuous attack. It is important to have preventive measures in place before getting a static IP, such as Internet security suites and router firewalls.


    Static IPs have the advantage in the quality and speed of hosting servers and running file transfer protocol sites. Conversely, servers based on a static IP have to be consistently on to host these functions. While most commercial servers are on all the time, the costs of constantly running a computer can be significant for a single person over time.


    Most computers come with Dynamic Host Configuration Protocol settings on by default. To set a static IP, the process is manual and relatively complex; in some cases, you may need external software to secure a static IP address. Moreover, many consumer-level ISPs do not support static IPs.

Limited Location

    When you obtain a static IP address for your computer, this address is matched with the Internet connection you were on at the time. Upon doing so, the address is already "used" -- you typically cannot get an Internet connection anywhere else without removing your static IP settings. This is particularly complex for people in Wide Lan Areas -- such as schools. In a typical campus, each area of the school uses a different subset of the overall Internet connection. If you're located at your dorm, for example, your static IP will not connect with the Internet in the other areas of the school.


    Computers are a rapidly evolving technology; a static IP computer running a server may become obsolete within a few years. Transferring the server settings from a static IP computer to a new computer is relatively complex; you would need to reserve the same IP on the new computer while losing the minimum amount of uptime. It is highly recommended to invest in an easily upgradeable computer to run a static IP server; as powerful desktop servers and supercomputers are typically designed for static IPs.

 Advantages of Static IP.
Ease of use for servers - register a DNS name for that IP address. Always connect via that DNS name, or via IP changes.

Disadvantages of Static IP.
Once known by a cracker - you are vulnerable, as it doesnt change, and they can take their time to crack your system open.

There is no need to mention firewalls av programs etc as a specific disadv of a static ip, because to viruses etc, it makes no difference if you are static or dynamic. it can be as little as 20 secs before infection on a non secured machine. The status of your IP will not affect this.

If you are a home user, and do choose a dynamic IP, it is also possible to get a Dynamic DNS. I use because my router handles that automatically. So no need for client apps to run on the server.
