My slave name server at ZoneEdit.com are down

It looks like the servers ns2.zoneedit.com and ns17.zoneedit.com are down. This mean you cannot access my blog (unless using a Google search).

I have my master DNS at my own computer and uses Zonedit.com for slave name servers. Zoneedit assignes each domain I have with two name servers. Unfortunately both of them are down for "lesc.se".

Protocol decoder for Internet based protocol

The ASN.1 language is a good language for specifying protocols. It is widely used by the telecommunications industry. However it is seldom good for "Internet based" protocols. For example IP/TCP/UDP/PPP.

For these kinds of protocols you have to have some other approach. One approach is to write your own language specification (grammar) and a compiler for this. From my own experience this is a risky path because you have to think really carefully how you design the grammar and compiler.

Does anyone know of any open or free implementations for a grammar and compiler that is suitable for Internet based protocols?
