Noah's Favorite Networking References

The following is a list of networking references that I refer to. I find that I need a centralized location for places that I go to all the time. Yes I know that that is what the "favorites" tab is for, but I routinely use, 3 different systems and have another 3 that I am on frequently if less than routinely. I won't mention the number of systems that I am on only occasionally. Keeping all those systems in sync is a pain so here is my list.

• Ethernet OUIs and Types
  • IEEE registered Ethernet OUIs
  • IEEE registered EtherTypes



• IP addresses and Domain Names
  • American Registry for Internet Numbers
  • A link to all the other Regional Internet Registries (RIRs) sites
  • Internet Assigned Numbers Authority (IANA) Includes links to all the cc and generic top level domains
  • Domain Dossier does several related whois searches and also looks at DNS records. Sort of an all in one site.
  • IP Locator Find location information about an IP address
  • Find the location of an IP address
  • Netcraft maintains a lot of information about web servers. I use it to locate web sites when I know part of a name. For example, search for "stratus" and you get 80 web servers (as of August 4th 2007) with the string stratus in their name (only a few are affiliated with Stratus Technologies).
  • registered IP Multicast addresses.
  • Bogons are IP addresses that should never be seen on the Internet. They are:
    • RFC 1918 defines the address space for private internets
    • RFC 3330 defines other IP address blocks that should not be used
    • The Team Cymru Bogon List page lists others as well as their history.



• Port Numbers
  • Well known and Registered Port Numbers
  • SANS trojan port number page
  • Commodon Communications maintains a list of trojan/well known ports.
  • Institute for Security and Open Methodologies Open Protocol Resource Project (OPRP) The nice thing about this page verus the previous pages is that it provides URLs rather than just a name. The URLs aren't always useful but they are better than nothing.



• Standards
  • RFCs
    • search for an RFC on the official RFC site. The nice thing about this search is besides getting the RFC you get information on updates to it.
    • official RFC database home page there is a link to search page from here so the above link is redundant - but faster (fewer clicks)
  • IEEE 802 PDFs



• Cisco pages that I found useful
  • documentation
  • Hardware Troubleshooting Index Page
  • Technical support page
  • MIB locator



• Microsoft Windows
  • Microsoft sites.
    • XP Home Page
    • Windows Server 2003 Home Page
    • Windows 2000 Home Page
    • Windows 2000 Documentation
    • TechNet Home Page
    • The Cable Guy
    • MSDN Home Page
    • Microsoft Communication Protocol Program (MCPP)
  • Microsoft related Sites
    • EventID.Net Primarily for EventID lookups but some other stuff as well
    • WinGuide Guides, general info and tutorials
    • KB Alertz Knowledge Base lookups HOWTOs, FAQs, and Guides



• Linux
  • Guide to IP Layer Network Administration with Linux
  • The Linux Documentation Project



• General Internet statistics
  • Internet Traffic Report
  • University of California Irvine
  • Looking glass servers
    These are servers that let you do a traceroute or a ping from them back to your or to any other host. They are a great way to confirm if a problem reaching a host is at your end or the host's end. It also lets you estimate route trip time.
    • a large world wide list of looking glass servers
    • Sprint (Conveniently provides your host name or IP address as the default target)
  • SenderBase keeps track of domains that are sending E-mails. It is used by spam blockers. One thing you can do is search a domain and see how much mail hosts in that domain are sending.



• These pages all allow you test something or find something out about your system
  • "Shield's UP" will test you local host to see what ports it has open as well as some other things. It will show you what IP address you are using and try to resolve you host name.
  • The ICSI NetalyzrLearn a lot of interesting things about your host's network connect and capabilities - requires java
  • This page just gives you your IP address and host name
  • projectip gives you information about your browser as well as your IP adress.
  • Speed tests
    • DSL Reports will give you an idea of your download and upload bandwidth capabilities.
    • numion
    • Audit My PC
    • National Broadband Plan requests the type of locataion and address (no idea what happens if you lie)
    • Speedtest.net
    • Speakeasy.net



• Security related sites.
  • Government
    • Compuer Crime and Intellectual Property Section of the Criminal Justice Division of the U.S. Dept. of Justice
    • National Security Agency Security Recommendation Guides for all sorts of systems
    • National Checklist Program (NCP) Security checklits for all kinds of things
  • Non-government
    • CERT (Computer Emergency Response Team) Coordination center
    • SANS (SysAdmin, Audit, Network, Security) Institute has security classes and sponsors a security certification. Part of the certification process is a research paper so they have a large number of papers spanning a wide variety of topics. The level of papers varies widely but some are really excellent.
    • The Ethical Hacker web site has an interesting collection of original articles and links about foensics, pen testing and incident response.
    • AV is an independent evaluation of anti-virus software
    • Insecure.org
    • Database of Smurf amplifiers which includes the ability to check on a subnet as well



• Tools
  • Cooperative Association for Internet Data Analysis (CAIDA) tools page
  • web based subnet calcuator
  • DNSstuff.com Multiple on-line tools including whois, traceroute, IP information, country code identifier and zip code location lookups
  • This site will convert a string of ASCII/HEX/Unicode in all of the above



• WiFi Locations
  • Anchor Free WiFi Location
  • Wi-Fi Free Spot Wifi locator
  • JiWire



• The phone system
  • LincMad Telephone Area Codes and Splits Maps of area codes, history of changes and planned changes
  • North American Numbering Plan (NANP) has a bunch of information about the phone system
  • area code maps
  • exchange locator Locate an exchange within an area code. It limits you to only 5 lookups within a 48 hour period but it is the only site I have found that does this.
  • DNSstuff.comlocation a phone number. US phone numbers can be located by area code and exchange (enter AAA-XXX-NNNN under "Area Code & ZIP Lookup). International (or US) phone numbers by country code (enter +CC-NUMBER under Phone Lookup)
  • World Telephone Numbering Guide lists a bunch of information about telehone dialing across the world. My primary use is the international dialing prefixes but there is other stuff as well
  • fone finder Another tool to find the location of phone numbers. Also will search for exchanges based on zip code, city name, does international searches as well.



• History
  • Wayback MachineThis site archives web sites, if what you found last week isn't there this week try here.
  • If you have a web page reference (URL) that doesn't appear to exist anymore or the information has changed and no longer contains what you are looking for try looking through the google cache by searching for cache:URL. No spaces between the directive cache: and the start of the URL. For example: cache:www.stratus.com
