Page Instructions


Main Page/Account Page


The Main page holds the account summary of your SNS@ISC package. There are two major components in the page - Account Summary Panel and SNS@ISC Traffic Graph. The Account Summary panel will reflect the information you modify within your SNS@ISC account. The SNS@ISC Traffic graph provides you with detailed information of traffic of your network based on the region of your choice and range of time.



The TSIG Keys page provides you with the information regarding your TSIG keys currently utilized by the server, key information, and the key in BIND@ISC format. You can add a new TSIG Key by clicking Add a new TSIG Key button, select the algorithm you would like to utilize, and save the key.

Transaction Signature Key is used primarily by the Domain Name System to provide a means of authenticating updates to a Dynamic DNS database, although it can be used between servers and for regular quries. TSIG uses shared secret keys and one-way hashing to provide a cryptographically secure means of identifying each endpoint of a connection as being allowed to make or respond to a DNS update.

Algorithm Options

Algorithm Output Size (bits) Key Size (bits)
SHA-256 256 32
SHA-512 512 64
MD5 128 32

Source Servers


Each SNS@ISC customer account is associated with one or more DNS source servers, or master servers, where the DNS zones hosted by SNS@ISC are made available by the customer. If the master server is open to zone transfer from unauthenticated parties then the TSIG keys are optional. However, to insure the security of your server, it is highly encouraged to utilize the TSIG to protect the zones.


Stats Page

The components on the page include:

  1. IP Address
  2. Input the IP Address of the server in which information is received from. Both IPv4 and IPv6 addresses can be utilized per source server.

  3. Description
  4. An optional section that provides information about your server.

  5. Priority
  6. The level of priority will control the order in which SNS@ISC will attempt to use these addresses. If there are two servers, one high and one medium, the query will be first directed to the one with the high priority, if the system receives no response, it will route the query to the medium priority server.

  7. TSIG Key
  8. Users have the option to implement the TSIG key authentication between the source server and the DM.

Publication Servers


The Publication Servers page provides the user with enabling nodes provided by different entities globally; for SNS@ISC COM, it includes Hurricane Electric, Cognet Communications, and Tata Communications.


Users are free to enable/disable the nodes they wish by clicking Enable/Disable button



The Zones page allows the user to add and configure the zones inputted. The user can search for a zone, examine the functionality and activity of the zone, and edit the information of the zone. The information from Zones section will also be reflected in the Stats page.

Stats Page


The Stats Page displays the Queries per Second data of your zones based on multiple variables defined by the time-frame of your data and the region. The page also provides you an aggregate information of your data; such as maximum number of queries in a range and average referrals in a range.


Stats Page

The page includes mulitple set of functions:

  1. Zone Selector Bar
  2. The Zone Selector Bar provides you with the option of searching through your zones, selecting the zones of interest for analysis, and removing zones from analysis. To find and select the zone of your interest, type in the zone you would like to analyze. After you found the zone of your interest, you can click on the zone or click Return/Enter on your keyboard.

  3. Graph Display
  4. The Graph Display is a user-interface that displays the queries per second at the instant and allows you to select a range of data . Hovering over the graph will display the information queries per second and time of the instant. Through clicking and dragging, you are capable of selecting a new range to examine. The resolution (time variable) will automatically be updated depending on the range you have selected.

  5. Graph Panel
  6. The Graph Panel allows you to modify the resolution of the graph display, select the global regions you would like to examine, utilize the Local Time Zone, modify the Graph Display by zooming out, and reload the graph in case the Graph Display freezes. The region list is a multi-select function. If you wish to select multiple regions, you can click CTRL-Click or Command-Click to select the regions of interest. To select/deselect regions from the list use the following command:

  7. Date Range Selector
  8. If you would like to analyze data during specific time period, you can use the Date Range Selector by inputting the From and To date. To implement the changes, click "Select Date." The Graph Display will refresh to impose the new date implementations.

  9. Overview Display
  10. The Overview Display provides you with a holistic image of the data that is currently visible in the Graph Display section. Similar to the Graph Display, you can select the range of your interest to zoom to a specific range.

Traffic Alerts


The Traffic Alerts page provides you the control to create notifications and set threshold limits for the amount of queries you receive.

Stats Page

The Traffic Alert page includes the following functions:

  1. Notification Options
  2. Users can select both, or one, options that Traffic Alert settings offer. You can enable or disable the notifications by simply unchecking the box or checking it.

  3. Smart Detection
  4. Smart Detection feature is an automated notification system designed by ISC engineers. The Smart Detection system detects any sudden shift in the trend or flow of queries. Users can designate the degree of senstivity of the system by selecting the Sensibility option that best fits their needs.

  5. Custom Thershold (QPS)
  6. Users have the option to be notified in regards to any change in the number of queries they receive through inputting the minimum and maximum number of queries per second. This function alerts the user when the system goes below, or above, the limits provided by the user.

Event Logs


The Event Logs page provides users an easy to search UI for the zones of interest and allows the user to download the zone of interest. The information is limited to activity that occured during the last hour and the last day.
