The software is free! It also provides an array of features like identity theft protection, online backups, and web security. Links has firewall settings on their SOHO routers. These firewalls protect the entire network. Most of the SOHO routers on the market today are wireless and provide all different types of wireless security including WAP 2 and also allowing for parental control. Firewalls are sometimes bought as a standalone device but most of the time these days they are built into the router. Software routers are installed on your computer and protect your computer from unwanted traffic.

The serial number doesn’t have to be a date, however, whenever a change to the zone file on the master DNS server is changed, the serial number must be increased by some value. That way, any slave server(s) will know that an update has been made, and they’ll do a zone transfer to get the newest copy of the zone file. The other numbers are explained in the file itself, The next record is the name server record. Here, it simply refers to itself as the name server, however, if you have several servers for a domain (one master, and at least one slave), you should put in an entry for each name server.
The MIX record also points to the same server. If you have more than one mail server, you can add several MIX records. The value is for priority; the lower the number, the higher the priority. A secondary mail server should therefore have a higher value (i. E. 20). Next are all the A records in no specific order. If there are many hosts, they can be put in alphabetically or numerically, whichever works. At the end, are the the CAME records. Since the “mailer” server is also the webserver, I placed the “www” to point to the same IP address as “mailer”.
