The IPv4 route-table problem will be with us for a long time, according to Cogent's Schaeffer. Some of Cogent's customers were affected by the surge in routes last week, though on their own equipment rather than Cogent's, Schaeffer said.
Conscientious ISPs may aggregate their own routes to help bring the tables back from the limit, but the reprieve will only be temporary, he said.
"We may, for a short period, fall below 512, but inexorably, the trend is larger tables."
