RIPE DNS Hostcount November 1993
by Marten Terpstra 03 Dec '93

03 Dec '93

Hi folks, Please find below the RIPE DNS hostcount for November 1993. - a few countries went down (ES and HR), probably due to connectivity problems. - it seems that in Europe, the UK has taken over first place from Germany (DE). - overall an increase of over 33,000 to 533,701 or a 6.7% incease from last month's count. - we are currently using the hostcount output (all the zones) to analyse the address usage in each of the top level domains. This is basically a breakdown of class A,B and C and the average usage on each of them. This is done for the IETF ALE working group. If you wish to have a copy of this, get on the ale list, or send me a private mail. For the ALE list, send a request to: ipv4-ale-request(a)ftp.com - also, we have run some tests to do the hostcount not only for Europe, but to include all other top level domains as well. This is both done to test the hostcount program, and to compare to the Zone overview as produced by Mark Lottor every quarter. Because these figures are used more and more to predict the growth rate of the Internet, we feel that one needs at least two different measurements for accurate figures. Our current thinking is that we will do a full worldwide DNS count in the X-mas period. - All output again on ftp.ripe.net:ripe/hostcount - history again appended.

Tickets of 2 and 3 strips can be bought on the bus or the tram but they are much more expensive. You have to validate the ticket yourself in the metro stations and in the trams (except on lines 4 and 13). In the buses the driver will validate the ticket. Amsterdam is divided into zones: the old city is in zone `Centrum' whereas CWI is in zone `Oost'. You need to count how many zones you will be travelling through (from the centre - CWI is 2 zones) and count up that number of strips on your ticket + 1 extra. So in the above example you will need to stamp the 3rd strip. In case of overflow you stamp the last strip of the first ticket and start counting the remaining strips on the next ticket. Confused? Warning: BEWARE of pickpockets in crowded places.
