The Top 20 and some deltas

18 Jan '95

This is an auto-generated mail on Wed Jan 18 21:10:00 MET 1995 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.18Jan95 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas
by Tony Bates 04 Jan '95

04 Jan '95

This is an auto-generated mail on Wed Jan 4 21:10:01 MET 1995 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.04Jan95 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas
by Tony Bates 28 Dec '94

28 Dec '94

This is an auto-generated mail on Wed Dec 28 21:10:01 MET 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.28Dec94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas
by Tony Bates 14 Dec '94

14 Dec '94

This is an auto-generated mail on Wed Dec 14 21:10:01 MET 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.14Dec94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes.

The Top 20 and some deltas
by Tony Bates 07 Dec '94

07 Dec '94

This is an auto-generated mail on Wed Dec 7 21:10:00 MET 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.07Dec94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.

The Top 20 and some deltas
by Tony Bates 30 Nov '94

30 Nov '94

This is an auto-generated mail on Wed Nov 30 21:10:01 MET 1994 As stated above this is auto-generated so it is not checked before it leaves my workstation. This is a list of the "Top 20" players who if CIDRizing at the AS level could make a significant gain in the size of Internet routing tables. This may be an over-estimation but it is hoped that this can act as an incentive for the "Top 20" and others to look at their CIDR capability. This report is available as: ftp://ftp.ripe.net/cidr/stats/Top-20.30Nov94 The current (and of course this one today) report is always accessible as: ftp://ftp.ripe.net/cidr/stats/Top-20 A full summary of all the ASes seen in the Internet can be seen by looking in: ftp://ftp.ripe.net/cidr/stats/AS* Please also find a summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does some indication of ASes participating in CIDR. More information can be found in: ftp://ftp.ripe.net/cidr/stats/Delta.* Also, for a short time this gives details of any possibly interesting aggregates currently seen in the routing. Interesting here means not a aggregate made as a set of classful routes. This a daily snapshot of changes in classfull routes being withdrawn and added. the deltas are calculated over a rolling 7 day period. Please bear in mind this is purely a "snapshot" and a large flucuation could be caused by a connectivity problem for example. However, this does give some indication of service providers that are moving to classless routing.
